This timing applies to all configurations regardless of SPI_CLK polarity and which clock edges are being used to drive output data and capture input data
(1) P = This timing applies to all configurations regardless of SPI_CLK polarity and which clock edges are being used to drive output data and capture input data
(2) Related to the SPI_CLK maximum frequency
(3) 20 ns cycle time = 50 MHZ
(4) P = SPICLK period
(5) SPI_CLK phase is programmable with the PHA bit of the SPI_CH(i)CONF register
(6) B = (TCS + .5) × TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register and Fratio = Even >= 2.
(7) When P = 20.8 ns, A = (TCS + 1) × TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register.
When P > 20.8 ns, A = (TCS + 0.5) × Fratio × TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register.
(8) The IO timings provided in this section are applicable for all combinations of signals for SPI1 and SPI2. However, the timings are only valid for SPI3 and SPI4 if signals within a single IOSET are used. The IOSETs are defined in the following tables.
Note:

Supported frequency of Radar SPIA Peripheral mode is 40MHz in full cycle and 20MHz in Half cycle mode.

Supported frequency of Radar SPIB Peripheral mode is 20MHz in full cycle and 10MHz in Half cycle mode.
