Hi Forum Members,
I am using MC9S12A128 in one of my projects. I am using its SPI interface to communicate with MC68HC908AP16. The SPI communication works fine but sometimes it is found that the SPI port of MC9S12A128 fails to communicate and in turn it is found that the SPI port itself is of no use. The controller as such works fine except SPI port. What could be the possible reason(s) for this? Whether any care is needed from hardware/software design point of view for SPI?
Your earliest help in this regard will be highly appreciated.
Thanks in advance.
