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
general register. The corresponding IMFA or IMFB flag in TSR is set to 1 at the same time. The
valid edge or edges of the input capture signal are selected in TIOR.

TIOR settings are ignored in PWM mode, complementary PWM mode, and reset-synchronized
PWM mode.

General registers are linked to the CPU by an internal 16-bit bus and can be written or read by
either word access or byte access.

General registers are initialized to the output compare function (with no output signal) by a reset
and in standby mode. The initial value is H'FFFF.

8.2.9  Buffer Registers (BRA, BRB)

The buffer registers are 16-bit registers. The ITU has four buffer registers, two each in channels 3
and 4.

automatically transferred to GRA or GRB at compare match

A buffer register is a 16-bit readable/writable register that is used when buffering is selected.
Buffering can be selected independently by bits BFB4, BFA4, BFB3, and BFA3 in TFCR.

The buffer register and general register operate as a pair. When the general register functions as an
output compare register, the buffer register functions as an output compare buffer register. When
the general register functions as an input capture register, the buffer register functions as an input
capture buffer register.
