McSPI loopback mode

Z.X

Hi Champions,

Does the McSPI support the loopback mode for test? My customer want to verify their software on J6Eco EVM, and I don't find the description for the McSPI loopback in the TRM.

Hi Zhan,

MCSPI doesn't have loopback mode in hardware. You can short-circuit MOSI with MISO and disconnect the slave device to make a loopback.
