“1”. The PWM waveform will be output to P0[6].
is configured to push-pull output type.
0 = Push-pull output type.
1 = Open-drain output.
0 = Pull-up ON. The bit is configured to pull-up ON.
1 = Pull-up OFF. The bit is configured to pull-up OFF.
If user wants to use the P0[6] bit as PWM waveform output to P0[6], set the P0SEL (PWMCON[0]) to
This register functions as a general purpose I/O port. The initial value of P0 is FFh.
This register configures the P0 output type to the push-pull or open-drain. The initial P0 output type
This register is enables/disabled the internal pull-up in P0.
