FAQ NO : 1000485 Issue Date : Jun.28.11 Functions : General MPU/MCU How can I write programs in the flash memory connected to SuperH MCU? You have two options as described below.1. Writing programs with an emulator with the function that supports writing to an external flash memory. Please check the specification of your emulator.When you use Renesas Electronics E10A-USB emulator, pleas...

FAQ NO : 105660 Issue Date : Mar.25.09 Functions : Oscillation Circuit When multiplication ratio of internal PLL circuit is changed, it counts the PLL setting time by on-chip WDT. At this time, is the clock supplied to WDT a clock before rewriting frequency control register (FRQCR) or a clock after rewriting frequency cont... The clock supplied to WDT when multiplication ratio of internal PLL circuit is changed is the clock after rewriting frequency control register (FRQCR). The clock supplied to WDT doesn't stop though the inside of the processor stops temporari... Relevant Products SH7729R SH7727 SH7720 SH7709S SH7706 SH7705
FAQ NO : 102181 Issue Date : Mar.25.09 Functions : Bus State Controller/External Bus Interface Is it possible to switch between little Endian and big Endian? Yes, it is possible to switch between little endian and big endian by designating an MD5 pin. At the time of a power-on reset, big endian is engaged when MD5 is low; little endian is engaged when MD5 is high. This designation is effective for the...

FAQ NO : 102791 Issue Date : Mar.25.09 Functions : Cache Memory What is coherency ? Coherency means that data is matched between cache and external memory. For example, writing to external RAM is not performed if the cache is hit when the cache is used in write back mode. Unmatching of data between the cache and external RAM o...

FAQ NO : 102796 Issue Date : Mar.25.09 Functions : Cache Memory Is it possible to turn the cache OFF in the specific address space? Please use P2 area when using with cache OFF because cache is disabled in P2 area within the address spaces of SH-3 and SH3-DSP, and use P0 area when using with cache ON because cache is enabled in P0 area.

FAQ NO : 102920 Issue Date : Mar.25.09 Functions : Bus State Controller/External Bus Interface Is it possible to insert the wait state by using the WAIT pin, when CS2 space or CS3 space are connected to the SDRAM? The wait state is not inserted by using the WAIT pin for SDRAM space. Access cycle numbers for SDRAM space are adjusted by setting CAS latency, pre-charge completion wait cycle numbers and others in the Bus State Controller(BSC). Please refer to ...

FAQ NO : 105335 Issue Date : Mar.25.09 Functions : Subclock Is there any note when RTC is not used? When RTC is not used, the standby mode (software standby mode) cannot be canceled by IRQ, IRL, PINT and each interrupt of on-chip peripheral functions. Cancel the standby mode (software standby mode) by NMI or reset when RTC is not used. ... Relevant Products SH7729R SH7727 SH7720 SH7709S SH7706 SH7705 SH7710
FAQ NO : 102805 Issue Date : Mar.25.09 Functions : Subclock If the RTC is not required in an application, what steps should be taken to ensure correct operation of the device? Be sure to connect Vcc-RTC and Vss-RTC to a power supply even when not using RTC. Do not connect anything to XTAL2. SH7709S, SH7729R, SH7706, SH7727: Please pull up EXTAL2 to Vcc (Internal Power supply). SH7705: Please pull up EXTAL2 to V... Relevant Products SH7729R SH7727 SH7720 SH7709S SH7706 SH7705
FAQ NO : 105661 Issue Date : Mar.25.09 Functions : Bus State Controller/External Bus Interface What should be confirmed when it cannot access SDRAM? Please confirm the following. 1. Please confirm the clock ratio of internal clock (IΦ) and bus clock (BΦ) should NOT be IΦ:BΦ=1:1 In SH7709S/SH7729R/SH7706/SH7727, it is NOT possible to access SDRAM when it is IΦ:BΦ=1:1 (In SH7705/SH772...
