  • Field FRF reader - Frame format.
  • Field FRF writer - Frame format.
  • Register SSPCR0 reader
  • Field SCR reader - Serial clock rate. The value SCR is used to generate the transmit and receive bit rate of the PrimeCell SSP. The bit rate is: F SSPCLK CPSDVSR x (1+SCR) where CPSDVSR is an even value from 2-254, programmed through the SSPCPSR register and SCR is a value from 0-255.
  • Field SCR writer - Serial clock rate. The value SCR is used to generate the transmit and receive bit rate of the PrimeCell SSP. The bit rate is: F SSPCLK CPSDVSR x (1+SCR) where CPSDVSR is an even value from 2-254, programmed through the SSPCPSR register and SCR is a value from 0-255.
  • Field SPH reader - SSPCLKOUT phase, applicable to Motorola SPI frame format only. See Motorola SPI frame format on page 2-10.
  • Field SPH writer - SSPCLKOUT phase, applicable to Motorola SPI frame format only. See Motorola SPI frame format on page 2-10.
  • Field SPO reader - SSPCLKOUT polarity, applicable to Motorola SPI frame format only. See Motorola SPI frame format on page 2-10.
  • Field SPO writer - SSPCLKOUT polarity, applicable to Motorola SPI frame format only. See Motorola SPI frame format on page 2-10.
