Capture Control B Register
| ARMB | Arm B 0 (0): Input capture operation is disabled. 1 (1): Input capture operation as specified by CAPTCTRLB[EDGBx] is enabled. |
| ONESHOTB | One Shot Mode B 0 (0): Free running mode is selected. If both capture circuits are enabled, then capture circuit 0 is armed first after CAPTCTRLB[ARMB] is set. Once a capture occurs, capture circuit 0 is disarmed and capture circuit 1 is armed. After capture circuit 1 performs a capture, it is disarmed and capture circuit 0 is re-armed. The process continues indefinitely. If only one of the capture circuits is enabled, then captures continue indefinitely on the enabled capture circuit. 1 (1): One shot mode is selected. If both capture circuits are enabled, then capture circuit 0 is armed first after CAPTCTRLB[ARMB] is set. Once a capture occurs, capture circuit 0 is disarmed and capture circuit 1 is armed. After capture circuit 1 performs a capture, it is disarmed and CAPTCTRLB[ARMB] is cleared. No further captures will be performed until CAPTCTRLB[ARMB] is set again. If only one of the capture circuits is enabled, then a single capture will occur on the enabled capture circuit and CAPTCTRLB[ARMB] is then cleared. |
| EDGB0 | Edge B 0 0 (00): Disabled 1 (01): Capture falling edges 2 (10): Capture rising edges 3 (11): Capture any edge |
| EDGB1 | Edge B 1 0 (00): Disabled 1 (01): Capture falling edges 2 (10): Capture rising edges 3 (11): Capture any edge |
| INP_SELB | Input Select B 0 (0): Raw PWM_B input signal selected as source. 1 (1): Output of edge counter/compare selected as source. When this bitfield is set to 1, the internal edge counter is enabled and the rising and/or falling edges specified by the CAPTCTRLB[EDGB0] and CAPTCTRLB[EDGB1] fields are ignored. The software must still place a value other than 00 in either or both of the CAPTCTLRB[EDGB0] and/or CAPTCTRLB[EDGB1] fields in order to enable one or both of the capture registers. |
| EDGCNTB_EN | Edge Counter B Enable 0 (0): Edge counter disabled and held in reset 1 (1): Edge counter enabled |
| CFBWM | Capture B FIFOs Water Mark |
| CB0CNT | Capture B0 FIFO Word Count |
| CB1CNT | Capture B1 FIFO Word Count |
