Initial
Value R/W Description
0 R/W I/O Control B1 and B0
0 R/W When IOB2 = 0,
00: No output at compare match
01: 0 output to the FTIOB pin at GRB compare match
10: 1 output to the FTIOB pin at GRB compare match
11: Output toggles to the FTIOB pin at GRB compare
When IOB2 = 1,
00: Input capture at rising edge at the FTIOB pin
01: Input capture at falling edge at the FTIOB pin
1X: Input capture at rising and falling edges of the FTIOB

1 Reserved
This bit is always read as 1.
