System Options Register 2 (SOPT2)
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
Analog Comparator to Input Capture Enable — This write-once bit connects the output of ACMP1 to TPM1
input channel 0.
0 ACMP1 output not connected to TPM1 input channel 0.
1 ACMP1 output connected to TPM1 input channel 0.
TPM2CH1 Pin Select— This write-once bit selects the location of the TPM2CH1 pin of the TPM2 module.
0 TPM2CH1 on PTB4.
1 TPM2CH1 on PTA7.
TPM2CH0 Pin Select— This write-once bit selects the location of the TPM2CH0 pin of the TPM2 module.
0 TPM2CH0 on PTA1.
1 TPM2CH0 on PTA6.
TPM1CH1 Pin Select— This write-once bit selects the location of the TPM1CH1 pin of the TPM1 module.
0 TPM1CH1 on PTB5.
1 TPM1CH1 on PTC1.
TPM1CH0 Pin Select— This write-once bit selects the location of the TPM1CH0 pin of the TPM1 module.
0 TPM1CH0 on PTA0.
1 TPM1CH0 on PTC0.
