I'm using MQX 4.1 on some Kinetis µC (K70, K60...)
I'm looking for a way to use the SPI Chip Select signal with Strobe option.
DataSheet indicate SPIx_MCR_PCSSE have to set to 1. By this way PCS5 become a strobe signal.
§53.2.4 of K60p144 datasheet:
When the DSPI is in master mode and the MCR[PCSSE] bit is set, the PCSS signal acts
as a strobe to an external peripheral chip select demultiplexer, which decodes the PCS0 -
PCS4 signals, preventing glitches on the demultiplexer outputs.
But I not found in the MQX_IO_USer_Guide.pdf any way to use this mode.
Are they a IO_Ctl command to do this? I read in the MQX code, I'm not find a line which set SPI_MCR_PCSSE bit.???
Thank for your help
