I would like to change the operation of the MIBSPI1CS[4] line to idle low and active high. I am able to change the idle level using the spiREG1->DEF register, but I am unable to change the active state polarity using either spi1DAT1.CSNR or the spiREG1->DAT1 register. Is there a setting or a capability that I am missing? I am using SPI1 in MIBSPI mode. The data sheet mentions CS[3:0] in some locations and CS[4:0] is others, but there are six total CS lines. Are there some features that are not available on all the CS lines?
I am using Halcogen 04.05.01.
