    • Removed 'Mixed' Pin Group for SAU_I2C, SAU_SPI and SAU_UART
    • Replaced 'Custom' Operation Mode by 'Custom (No Mixed)' for SAU_SPI and SAU_UART

    • Disabled SAU channel in other operation modes when one mode is used in SAU_I2C, SAU_SPI, SAU_UART
• Corrected LPM macro name LPM_SNOOZE_END_SCI0_ADDRESS_MATCH to LPM_SNOOZE_END_SCI0_ADDRESS_MISMATCH
• Removed the deprecated IICRSV (Communication reservation) setting in IICA master
• The pin names of r_ssi have been fixed for RA8M1/D1/T1/E1/E2 devices to match the HW user manual. Existing  projects for the affected devices with SSIE pins configured shall need to be reconfigured
• In accordance with the update to the new security policy, the public key injection APIs for RSA and ECC algorithms have been removed in the r_rsip_key_injection module. This change only affects RSIP-E51A devices.
• Changed the method of releasing Ether-related tasks from waiting and the method of retrieving the MAC address
• USB pipe selection in the Host/Peripheral stack has been removed. Pipes are now selected automatically at run-time.
  • Users may now refer to the type member in the usb_event_info structure to determine which write or read event has completed.
  • Please check and update your application code if the project build fails due to undefined macros USB_CFG_PCDC_BULK_IN or USB_CFG_PHID_INT_IN; for example:
    • In a PCDC+PCDC or PCDC+PVND Composite Baremetal project, update the condition for USB_STATUS_WRITE_COMPLETE/USB_STATUS_READ_COMPLETE status from if (USB_CFG_PCDC_BULK_IN/OUT == event_info.pipe) to if (USB_CLASS_PCDC == event_info.type)
    • In a PHID+PHID Composite FreeRTOS project, update the condition for USB_STATUS_WRITE_COMPLETE status from if (USB_CFG_PHID_INT_IN == p_usb_basic_event->pipe) to if (USB_CLASS_PHID == p_usb_basic_event->type)
  • Please note that R_USB_Read() and R_USB_Write() APIs should only be called during the Data Transfer state. If called in any other state(such as Control Transfer, etc.), these functions will return FSP_ERR_USB_FAILED
• Removed the element handle in the BLE MESH ACCESS instance control struct
• Removed deprecated BSP_PACKED macro
• The key management specification in the r_rsip_protected module has been revised. The main change is that the specification of the rsip_wrapped_key_t structure, which manages wrapped key, has been changed, and its members are now type and * p_value. The member type indicates the key type managed by this structure, and the member * p_value indicates the pointer to the address where the actual wrapped key is located. Previously, the actual wrapped key value was managed in rsip_wrapped_key_t, but the new specification instead stores a pointer to the address where the key is located. With this change, users must initialize each member (type and * p_value) when declaring rsip_wrapped_key_t variable. In addition, since the key type is initialized in advance as described above, it is no longer necessary to specify it in APIs such as key generation, so the argument key_type has been removed from the related APIs. For specific instructions, please refer to the Examples on the r_rsip_protected page of the FSP User Manual.
• The behavior of MCUboot images and flash areas is now configured via the Solution project instead of via MCUboot stack properties

Fixes and Improvements

• RA2 compiler/linker changes:
  • Default optimization is now -Oz (max optimize for size)
  • By default, content will be placed in the flash 'gap' (area between vector table and OFS registers)
• Added constraint for limiting TrustZone selection for non-secure projects in MCUboot
• Add multiple instance support for OSPI_B DOTF
• r_sci_b_lin:
  • Add support for selecting the number of base clock cycles per bit period in e2 studio to control the SCI base clock frequency
  • R_SCI_B_LIN_BaudCalculate now ignores the input parameter sci_b_lin_baud_setting_t::bus_conflict_clock when calculating the baud rate because the bus conflict clock divider cannot be easily selected unless the SCI base clock frequency setting is already known. This parameter may be removed in a future major version of FSP.
  • Update usage notes to improve description of how to select an appropriate bus conflict clock divider when using bus conflict detection
• CMSIS-NN updated to version 7.0.0
• Updated the constraint logic of the properties 'ECDSA Scratch Buffer Size (Bytes)' and 'ECDH Scratch Buffer Size (Bytes)' for rm_netx_secure_crypto module to avoid negative values

• Fix various spelling mistakes throughout codebase
• Fixed ADC group priority setting
• Fixed ADC_B issue where channels 19 and 23-28 may not have been correctly selectable for virtual channels

• Removed const from p_context declarations allowing users to point to non-const data
• Fix missing/incorrect constraint on PLL Input Frequency for RA4 and RA6 MCUs
• Segger JLink version updated to v8.44a

• EWARM version 9.60.4 does not contain support for RA0E2, RA2L2, RA2T1, RA4C1 and RA8P1. To develop with IAR for these devices, it is necessary to install a support patch file for which can be downloaded by EWARM v9.60.4 users from the IAR MyPages system

• Due to limitations in RASC, Projects fail to build if there are files with the same name in a build group. To fix this issue, create files with the same name in different build groups. For known issues in the tools, please refer to the respective tool's release notes, e² Studio RN
