Section 10 16-Bit Timer Pulse Unit (TPU)
Bit 0—Input Capture/Output Compare Flag A (TGFA): Status flag that indicates the
occurrence of TGRA input capture or compare match.
Bit 0: TGFA
0
1
Description
[Clearing condition]
(Initial value)
When 0 is written to TGFA after reading TGFA = 1
[Setting conditions]
• When TCNT = TGRA while TGRA is functioning as output compare
register
• When TCNT value is transferred to TGRA by input capture signal while
TGRA is functioning as input capture register
Note: Cleared by DMAC transfer initiated by TGFA.
10.2.6 Timer Counters (TCNT)
Channel 0: TCNT0 (up-counter)
Channel 1: TCNT1 (up/down-counter*)
Channel 2: TCNT2 (up/down-counter*)
Channel 3: TCNT3 (up-counter)
Channel 4: TCNT4 (up/down-counter*)
Channel 5: TCNT5 (up/down-counter*)
Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Initial value: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
R/W: R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W
Note: * These counters can be used as up/down-counters only in phase counting mode (or
when counting overflows/underflows on another channel in phase counting mode). In
other cases they function as up-counters.
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 and
software standby mode. They are not initialized by the module standby function.
The TCNT counters cannot be accessed in 8-bit units; they must always be accessed as a 16-bit
unit.
