Note:
13.3.7
The timer Z has two TCNT counters (TCNT_0 and TCNT_1), one for each channel. The TCNT
counters are 16-bit readable/writable registers that increment/decrement according to input clocks.
Input clocks can be selected by bits TPSC2 to TPSC0 in TCR. TCNT0 and TCNT 1
increment/decrement in complementary PWM mode, while they only increment in other modes.
The TCNT counters are initialized to H'0000 by compare matches with corresponding GRA, GRB,
GRC, or GRD, or input captures to GRA, GRB, GRC, or GRD (counter clearing function). When
the TCNT counters overflow, an OVF flag in TSR for the corresponding channel is set to 1. When
TCNT_1 underflows, an UDF flag in TSR is set to 1. The TCNT counters cannot be accessed in 8-
bit units; they must always be accessed as a 16-bit unit.
