PWM6 and PWM7 clock source select
PWM6 and PWM7 used the same Engine clock source, both of them use the same pre-
scalar
00 = Clock source from external crystal clock (4 ~ 24MHz)
01 = Reserved
10 = Clock source from HCLK
11 = Clock source from internal 22.1184 MHz oscillator clock
PWM4 and PWM5 clock source select
PWM4 and PWM5 used the same Engine clock source, both of them use the same pre-
scalar
