Description
The 7203 is a 2K x 9 dual-port FIFO memory that loads and empties data on a first-in/first-out basis. The device uses Full and Empty flags to prevent data overflow and underflow. It has a Retransmit (RT) capability that allows for reset of the read pointer to its initial position when RT is pulsed LOW. It is designed for those applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.

Microsecond Resolution Timing
Timer1 is reserved for the FreeRTOS ticks, which is running with the 32 kHz clock giving a resolution of ~30.5 microseconds. If I wanted to get the current execution time in a smaller resolution of microseconds, is there somewhere where the 16/32 MHz XTAL or 48/ ...
