I am trying to hold the assertion of the chip select line between byte transfers to a device.
Example: Assert CSn->Send byte->CSn stays asserted->Send next byte....and so on until byte by byte transfer is complete.
On the FRDM-KL27, I can configure the CSn as a gpio. I can then control the CSn as needed in firmware.
Not so on the K64. Or is it????
Before you say...just make CSn continuous over transfers by using the CONT bit, I have to warn you. According to SDK 2.0, I can only set this bit if my CPHA is equal to 1, which it is not. Setting it to 1 would violate the slave devices specs.
I am using SDK 2.0 with IAR EWARM.
So...what would you do K64 ninjas?
