14.3.6
TCNT are 16-bit counters.
The initial value of TCNT is H'0000.
14.3.7
TGR are 16-bit registers.
TGRC and TGRD can also be designated for operation as buffer registers*. The initial value of
TGR is H'FFFF.
Note: *TGR buffer register combinations are TGRA—TGRC and TGRB—TGRD.
14.3.8
TSTR is a 16-bit readable/writable register that selects TCNT operation/stoppage for channels 0 to
3.
