TRIGPOL=B_0x0, TRIGEN=B_0x0, TRIGSEL=B_0x0
SPI autonomous mode control register
| TRIGSEL | trigger selection (refer Section: Description of SPI interconnections). … Note: these bits can be written only when SPE=0. 0 (B_0x0): spi_trg0 is selected 1 (B_0x1): spi_trg1 is selected 15 (B_0xF): spi_trg15 is selected |
| TRIGPOL | trigger polarity Note: This bit can be written only when SPE=0. 0 (B_0x0): trigger is active on raising edge 1 (B_0x1): trigger is active on falling edge |
| TRIGEN | HW control of CSTART triggering enable Note: if user cannot prevent trigger event during write, the TRIGEN must be changed when SPI is disabled 0 (B_0x0): HW control disabled 1 (B_0x1): HW control enabled |
