b0 IOA0 TRGGRA control bit
b1 b0
R/W
b1 IOA1
0 0: Input capture to TRGGRA at the rising edge
R/W
0 1: Input capture to TRGGRA at the falling edge
1 0: Input capture to TRGGRA at both edges
1 1: Do not set.
b2
IOA2 _{TRGGRA mode select bit} ⁽¹⁾ Set to 1 (input capture) for the input capture function.
R/W
b3 BUFA TRGGRC register function 0: Not used as the buffer register of the TRGGRA register R/W
select bit
1: Used as the buffer register of the TRGGRA register
b4 IOB0 TRGGRB control bit
b5 b4
R/W
b5 IOB1
0 0: Input capture to TRGGRB at the rising edge
R/W
0 1: Input capture to TRGGRB at the falling edge
1 0: Input capture to TRGGRB at both edges
1 1: Do not set.
b6
IOB2 _{TRGGRB mode select bit} ⁽²⁾ Set to 1 (input capture) for the input capture function.
R/W
b7 BUFB TRGGRD register function 0: Not used as the buffer register of the TRGGRB register R/W
select bit
1: Used as the buffer register of the TRGGRB register
Notes:
1. When the IOA2 bit is set to 1 (input capture function), the TRGGRA register functions as an input capture
register.
2. When the IOB2 bit is set to 1 (input capture function), the TRGGRB register functions as an input capture
register.
