It seems that SPI1 PTI0 ALT4 (SPI1_MISO) and PTI1 ALT4 (SPI1_MOSI) do not work on MKM34Z256xxx7.
The lines stay low during communication attempt, however, PTH6 ALT3 (SPI1_PCS0)) and PTH7 ALT3
(SPI1_CLK) function properly. Switching PTI pins to ALT5 make them to work as required, except for the
swapped functionality (MISO <-> MOSI).
Tested on a custom board and on MKM34Z7 tower board. Is it a bug on a silicon or I am doing something
Can anybody confirm, please?
