Section 13 Timer Z
When the counter is incremented or decremented, the IMFA flag of channel 0 is set to 1, and when
the register is underflowed, the UDF flag of channel 0 is set to 1. After buffer operation has been
designated for BR, BR is transferred to GR when the counter is incremented by compare match
A0 or when TCNT_1 is underflowed. If the or /2 clock is selected by TPSC2 to TPSC0 bits,
the OVF flag is not set to 1 at the timing that the counter value changes from H'FFFF to H'0000. If
the /4 or /8 clock is selected by TPSC2 to TPSC0 bits, the OVF flag is set to 1.
