Section 15
Note:
15.3.6
The TCNT registers are 16-bit readable/writable counters. The TPU has four TCNT counters, one
for each channel.
The TCNT counters are initialized to H'0000 by a reset.
The TCNT counters are not initialized in standby mode, sleep mode, or module standby.
15.3.7
The TGR registers are 16-bit registers. The TPU has 16 TGR registers, four each for channels 0
and 3. TGRC and TGRD can also be designated for operation as buffer registers*. The TGR
registers are initialized to H'FFFF by a reset. These registers are not initialized in standby mode,
sleep mode, or module standby.
Note: * TGR buffer register combinations are TGRA—TGRC and TGRB—TGRD.
