Bit 0—Input Capture/Output Compare Flag A (TGFA): Status flag that indicates the
occurrence of TGRA input capture or compare match.

Note: * These counters can be used as up/down-counters only in phase counting mode or when
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.
