Note: * These counters can be used as up/down-counters only in phase counting mode or when
counting overflow/underflow on another channel. 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.
The TCNT counters cannot be accessed in 8-bit units; they must always be accessed as a 16-bit
unit.
