10.3.6 Timer Counter (TCNT)
The TCNT registers are 16-bit readable/writable counters. The MTU has five TCNT counters, one
for each channel.
The TCNT counters are initialized to H'0000 by a reset and in hardware standby mode.
The TCNT counters cannot be accessed in 8-bit units; they must always be accessed as a 16-bit
unit.
10.3.7 Timer General Register (TGR)
The TGR registers are dual function 16-bit readable/writable registers, functioning as either output
compare or input capture registers. The MTU has 16 TGR registers, four each for channels 0, 3,
and 4 and two each for channels 1 and 2. TGRC and TGRD for channels 0, 3, and 4 can also be
designated for operation as buffer registers. The TGR registers cannot be accessed in 8-bit units;
they must always be accessed as a 16-bit unit. TGR buffer register combinations are
TGRATGRC and TGRBTGRD. The initial value of TGR is H'FFFF.
