Description
Reserved
This bit is always read as 1.
I/O Control D2
Selects the GRD function.
0: GRD functions as an output compare register
1: GRD functions as an input capture register
I/O Control D1 and D0
When IOD2 = 0,
00: No output at compare match
01: 0 output to the FTIOD pin at GRD compare match
10: 1 output to the FTIOD pin at GRD compare match
11: Output toggles to the FTIOD pin at GRD compare
match
When IOD2 = 1,
00: Input capture at rising edge at the FTIOD pin
01: Input capture at falling edge at the FTIOD pin
1X: Input capture at rising and falling edges at the FTIOD
pin
Reserved
This bit is always read as 1.
I/O Control C2
Selects the GRC function.
0: GRC functions as an output compare register
1: GRC functions as an input capture register
I/O Control C1 and C0
When IOC2 = 0,
00: No output at compare match
01: 0 output to the FTIOC pin at GRC compare match
10: 1 output to the FTIOC pin at GRC compare match
11: Output toggles to the FTIOC pin at GRC compare
match
When IOC2 = 1,
00: Input capture to GRC at rising edge of the FTIOC pin
01: Input capture to GRC at falling edge of the FTIOC pin
1X: Input capture to GRC at rising and falling edges of the
FTIOC pin
