Section 10 16-Bit Timer Pulse Unit (TPU)
10.3.6
TCNT is a 16-bit readable/writable counter. The TPU has six TCNT counters, one for each
channel.
TCNT is initialized to H'0000 by a reset or in hardware standby mode.
TCNT cannot be accessed in 8-bit units. TCNT must always be accessed in 16-bit units.
10.3.7
TGR is a 16-bit readable/writable register with a dual function as output compare and input
capture registers. The TPU has 16 TGR registers, four each for channels 0 and 3 and two each for
channels 1, 2, 4, and 5. TGRC and TGRD for channels 0 and 3 can also be designated for
operation as buffer registers. The TGR registers cannot be accessed in 8-bit units; they must
always be accessed in 16-bit units. TGR and buffer register combinations during buffer operations
are TGRA−TGRC and TGRB−TGRD.
