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 in TCRW to 1. When TCNT overflows (changes from H'FFFF to H'0000), the OVF
flag in TSRW is set to 1. If OVIE 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 by a reset.

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
When IOC2 = 1,
00: Input capture to GRC at rising edge of the FTIOC
01: Input capture to GRC at falling edge of the FTIOC
