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 edge and falling edge of the

FTIOC pin

Timer Counter (TCNT)

TCNT is a 16-bit readable/writable up-counter. The clock source is selected by bits CKS2 to

CKS0 in TCRW. TCNT can be cleared to H'0000 through a compare match with GRA by setting

the CCLR bit in TCRW to 1. When TCNT overflows (changes from H'FFFF to H'0000), the OVF

flag in TSRW is set to 1. If the OVIE bit in TIERW is set to 1 at this time, an interrupt request is

generated. TCNT must always be read or written in 16-bit units; 8-bit access is not allowed.

TCNT is initialized to H'0000.
