Description
PWM Prescaler
The prescaler divides down the PWM input clock (either the system clock or the
PWMIN external input). This field is buffered. Changes to this field take effect at
the next PWM reload event. Reads always return the values from the
temporary holding register.

PWM Deadband Register
The PWM Deadband (PWMDB) Register, shown in Table 50, stores the 8-bit PWM dead-
band value. This register determines the number of system clock cycles inserted as dead-
time in complementary output mode. The minimum deadband value is 1.

PWMDB
PWM Dead band
Sets the PWM dead band period for which both PWM outputs of a
complementary PWM output pair are deasserted.
Note: This register can only be written when PWEN is cleared.
