10.2.6
Note: * These counters can be used as up/down-counters only in phase counting mode or when counting
The TCNT registers are 16-bit counters. The TPU has six 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.
10.2.7
The TGR registers are 16-bit registers 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 are initialized to H'FFFF by a reset, and
in hardware standby mode.
The TGR registers cannot be accessed in 8-bit units; they must always be accessed as a 16-bit unit.
Note: * TGR buffer register combinations are TGRA—TGRC and TGRB—TGRD.
10.2.8
TSTR is an 8-bit readable/writable register that selects operation/stoppage for channels 0 to 5. TSTR is initialized to H'00
by a reset, and in hardware standby mode. When setting the operating mode in TMDR or setting the count clock in TCR,
first stop the TCNT counter.
