Table 7-17. PWM LSB x Register

PWM LSB x Register (PWL0R) (Address = 0x88)

(PWL1R) (Address = 0x8A)

(PWL2R) (Address = 0x8C)

(PWL3R) (Address = 0x8E)

Bit(s) Value Description

7:6 write The least significant two bits for the Pulse Width Modulator count are stored.

5:1 These bits are ignored.

0 0 PWM output High for single block.

1 Spread PWM output throughout the cycle.

Table 7-18. PWM MSB x Register

PWM MSB x Register (PWM0R) (Address = 0x89)

(PWM1R) (Address = 0x8B)

(PWM2R) (Address = 0x8D)

(PWM3R) (Address = 0x8F)

Bit(s) Value Description

7:0 write

The most significant eight bits for the Pulse Width Modulator count are stored.

With a count of "n", the PWM output will be High for "n + 1" clocks out of the

1024 clocks of the PWM counter.
