In controller mode, the baud rate of the MCSPI serial clock is programmable.
An internal reference clock, SPICLKREF, is used as input of a programmable divider (the MCSPI_CHCONF_0/1/2/3[5-2] CLKD bit field) to generate the bit rate of the serial output clock SPICLK. Table 13-27 summarizes the supported divisor values.
| Divider | Clock Rate |
|---|---|
| 1 | 50 MHz(1) |
| 2 | 25 MHz(1) |
| 4 | 12.5 MHz |
| 8 | 6.25 MHz |
| 16 | 3.125 MHz |
| 32 | 1.5625 MHz |
| 64 | 781.25 kHz |
| 128 | 390 kHz(2) |
| 256 | 195 kHz(2) |
| 512 | 97.7 kHz(2) |
| 1024 | 48.8 kHz(2) |
| 2048 | 24.4 kHz(2) |
| 4096 | 12.2 kHz(2) |
