Description
I/O Control A1 and A0
When IOA2 = 0,
00: No output at compare match
01: 0 output to the FTIOA pin at GRA compare match
10: 1 output to the FTIOA pin at GRA compare match
11: Output toggles to the FTIOA pin at GRA compare
When IOA2 = 1,
00: Input capture at rising edge of the FTIOA pin
01: Input capture at falling edge of the FTIOA pin
1X: Input capture at rising and falling edges of the FTIOA
Description
Reserved
This bit is always read as 1.
Selects the GRD function.
