10.2.1
TCNT is an 8-bit readable/writable up-counter. When the output enable bit (OE) is set to 1 in
TCR, TCNT starts counting pulses of an internal clock source selected by clock select bits 2 to 0
(CKS2 to CKS0). After counting from H'00 to H'F9, the count repeats from H'00. When TCNT
changes from H'00 to to H'01, the PWM output is placed in the 1 state, unless the DTR value is
H'00, in which case the duty cycle is 0% and the PWM output remains in the 0 state.
TCNT is initialized to H'00 at a reset and in the standby modes, and when the OE bit is cleared to
0.
