PCLK3 — PWM Channel 3 Clock Select
PCLK2 — PWM Channel 2 Clock Select
PCLK1 — PWM Channel 1 Clock Select
Clock B is one of two clock sources which may be used for channels
2 and 3. These three bits determine the rate of clock B, as shown in
Table
0 = Clock B is the clock source for channel 3.
1 = Clock S1 is the clock source for channel 3.
0 = Clock B is the clock source for channel 2.
1 = Clock S1 is the clock source for channel 2.
0 = Clock A is the clock source for channel 1.
1 = Clock S0 is the clock source for channel 1.
