TCNT can be cleared to H'0000 by compare match with GRA or GRB or by input capture to GRA
or GRB (counter clearing function) in the same channel.
When TCNT overflows (changes from H'FFFF to H'0000), the OVF flag is set to 1 in TSR of the
corresponding channel.
When TCNT underflows (changes from H'0000 to H'FFFF), the OVF flag is set to 1 in TSR of the
corresponding channel.
The TCNTs are linked to the CPU by an internal 16-bit bus and can be written or read by either
word access or byte access.
Each TCNT is initialized to H'0000 by a reset and in standby mode.
10.2.8
The general registers are 16-bit registers. The ITU has 10 general registers, two in each channel.

A general register is a 16-bit readable/writable register that can function as either an output
compare register or an input capture register. The function is selected by settings in TIOR.
When a general register is used as an output compare register, its value is constantly compared
with the TCNT value. When the two values match (compare match), the IMFA or IMFB flag is set
to 1 in TSR. Compare match output can be selected in TIOR.
When a general register is used as an input capture register, rising edges, falling edges, or both
edges of an external input capture signal are detected and the current TCNT value is stored in the
