Pin Related to the 8-bit PWM Timer

The pin related to the 8-bit PWM timer is the P50/PWM pin.
● P50/PWM pin
This pin can be used as a general-purpose I/O port (P50) and for output of the interval timer or PWM timer
(PWM).
PWM:
While the pin functions as the interval timer, the square wave is output to the pin.
While the pin functions as the PWM timer, the PWM wave is output to the pin.
When the bit to control the output pin is set to the dedicated pin (CNTR: OE = 1), the P50/PWM pin
automatically functions as an output pin, regardless of the value of the port 5 data direction register
(DDR5: bit0), and as the PWM pin.
