CHOPCLK<6:0>: Chop Clock Divider bits
Value in 8.32 ns increments. The frequency of the chop clock signal is given by the following
expression:
expression:
Chop Frequency = 1/(16.64 * (CHOPCLK<6:0> + 1) * Primary Master PWM Input Clock Period)
bit 2-0
Unimplemented: Read as ‘0’
Note 1:
The chop clock generator operates with the primary PWM clock prescaler (PCLKDIV<2:0>) in the
PTCON2 register (
