16.2.7
The TGR registers are 16-bit registers with a dual function as output compare and input capture
registers. The TPU has 8 TGR registers, four for channel 0 and two each for channels 1, and 2.
TGRC and TGRD for channel 0 can also be designated for operation as buffer registers*. The
TGR registers are initialized to H'FFFF by a reset.
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.
16.2.8
TSTR is an 8-bit readable/writable register that selects operation/stoppage for channels 0 to 2.
TSTR is initialized to H'00 by a reset.
TCNT counter operation should be stopped when setting the operating mode in TMDR or the
TCNT count clock in TCR.
Bits 7 to 3—Reserved: Should always be written with 0.
