bit 9-3

CHOP<9:3>: Chop Clock Divider bits

Value in 8.32 ns increments. The frequency of the chop clock signal is given by the following

expression:

Chop Frequency = 1/(16.64 * (CHOP<7:3> + 1) * Primary Master PWM Input Clock Period)

Note:

The chop clock generator operates with the primary PWM clock prescaler (PCLKDIVL<2:0>) in the

PTCON2 register.
