Each TCNT is a 16-bit readable/writable register that counts pulse inputs from a clock source. The
clock source is selected by bits TPSC2 to TPSC0 in TCR.
TCNT0 and TCNT1 are up-counters. TCNT2 is an up/down-counter in phase counting mode and
an up-counter in other modes. TCNT3 and TCNT4 are up/down-counters in complementary PWM
mode and up-counters in other modes.
