// The Apollo IOM SPI interface supports only nCE (active low chip select)
// signals. For displays that use a SPI interface using active-high CS, the
// CS signaling must be driven via GPIO. The BSP therefore uses a GPIO to
// drive it, which will work for any display whether active high or low.
// The nCE0 signal corresponds to GPIO12 (AM_BSP_GPIO_IOM1_DISPLAY_CS) in the
// pin mapping.
// For the HAL calls that require a CS parameter, we'll give it 0 (for nCE0)
// via AMBSP_IOM_DISPLAY_NCE, we'll select IOM1 using AM_BSP_IOM_DISPLAY_INST.
