FIGURE 25-4:

PWM DUTY CYCLE EQUATION

The PWMx Counter ON Time Register and PWMx Counter OFF Time Register registers should be accessed as 16-bit

values.

25.11 EC-Only Registers

The registers listed in the EC-Only Register Summary table are for a single instance of the PWM. The addresses of

each register listed in this table are defined as a relative offset to the host “Base Address” defined in the EC-Only Reg-

ister Base Address Table.

The Base Address indicates where the first register can be accessed in a particular address space for a block instance.

15:0 PWMX_COUNTER_ON_TIME

This field determine both the frequency and duty cycle of the PWM

signal.

When this field is set to zero and the PWMX_COUNTER_OFF_-

TIME is not set to zero, the PWM_OUTPUT is held low (Full Off).
