11.3.11 Timer Counter (TCNT)
The TCNT counters are 16-bit readable/writable counters. This module has five TCNT counters,
one each for channels 0 to 4.
The TCNT counters must not be accessed in eight bits; they should always be accessed in 16 bits.

11.3.12 Timer General Register (TGR)
The TGR registers are 16-bit readable/writable registers. This module has eighteen TGR registers,
six for channel 0, two each for channels 1 and 2, four each for channels 3 and 4.
TGRA, TGRB, TGRC, and TGRD function as either output compare or input capture registers.
TGRC and TGRD for channels 0, 3, and 4 can also be designated for operation as buffer registers.
TGR buffer register combinations are TGRA and TGRC, and TGRB and TGRD.
TGRE_0 and TGRF_0 function as compare registers. When the TCNT_0 count matches the
TGRE_0 value, an A/D converter start request can be issued. TGRF can also be designated for
operation as a buffer register. TGR buffer register combination is TGRE and TGRF.
