13.2 PWM OUTPUT UNIT CONTROL REGISTERS
13.2.1 PWM Control Register (PWMC)
is shown in Figure 13-2.
is set.
The PWMC is an 8-bit register that controls the operating status of the PWM output pins (PWMn: n = 0, 1).
The PWMC can be read or written to with an 8-bit manipulation instruction or bit manipulation instruction. Its format
When RESET is input, PWMC is set to 05H, the PWMn pin is set to port mode, and the input state (output high impedance)
