Section 9 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.

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.

Note: * These counters can be used as up/down-counters only in phase counting mode or
Timer Counter (TCNT)
when counting overflow/underflow on another channel. In other cases they function
as up-counters.

:
When DTC is activated by TGIA interrupt while DISEL bit of MRB in DTC is 0
When 0 is written to TGFA after reading TGFA = 1
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
