PIO17
P1.7/PWM pin function select
0 = P1.7/PWM3_CH0 pin functions as GPIO P1.7.
1 = P1.7/PWM3_CH0 pin functions as PWM3_CH0 output.
5
PIO15
P1.5/PWM pin function select
0 = P1.5/PWM pin functions as P1.5.
1 = P1.5/PWM pin functions as PWM0_CH5 / PWM3_CH1 output.
When AUXR5[3:2].PWM3CH1P = 11, PIO15 = 1 , P1.5 define as PWM3_CH1.
When AUXR5[3:2].PWM3CH1P = 00 ,PIO15 = 1, P1.5 define as PWM0_CH5.
