COP Watchdog Clock Select — This write-once bit selects the clock source of the COP watchdog.
0 Internal 1-kHz clock is source to COP.
1 Bus clock is source to COP.
COP Window — This write-once bit selects the COP operation mode. When set, the 0x55-0xAA write sequence
to the SRS register must occur in the last 25% of the selected period. Any write to the SRS register during the
first 75% of the selected period will reset the MCU.
0 Normal COP operation
1 Window COP operation (only if COPCLKS = 1)
Analog Comparator to Input Capture Enable— This bit connects the output of ACMP to TPM1 input channel 0.
0 ACMP output not connected to TPM1 input channel 0.
1 ACMP output connected to TPM1 input channel 0.
TPM1CH1 Pin Select— This bit selects the location of the TPM1CH1 pin of the TPM1 module.
0 TPM1CH1 on PTB5.
1 TPM1CH1 on PTC1.
TPM1CH0 Pin Select— This bit selects the location of the TPM1CH0 pin of the TPM1 module.
0 TPM1CH0 on PTA0.
1 TPM1CH0 on PTC0.
