3. Customer uses interrupt to read SPI (MCSPI_transfer()) every 20us, but it will consume 5~6us, how to improve the speed?
This is one of the most asked question and let me tell you that some delay is expected due to MCSPI Register read operations involved inMCSPI_transferAPI.
NOTE: For every transfer we need to reconfigure few parameters like FIFO config, Data Length, Word Length etc.
Moreover, this delay is expected one to ensure proper functioning of the peripheral.
