R/(W)* Output Compare Flag A
Status flag that indicates the occurrence of TGRA compare
match.
[Clearing conditions]
When 0 is written to TGFA after reading TGFA = 1
[Setting conditions]
When TCNT = TGRA
Note: * Only 0 can be written, to clear the flag.
20.3.6 Timer Counters (TCNT)
The TCNT registers are 16-bit 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.
20.3.7 Timer General Registers (TGR)
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.
