PWM AND PWM2 TIMING REGISTERS

Table 74. Register 0xFE0C—PWM Rising Edge Timing (PWM Pin)

Bits

Bit Name

R/W

Description

[7:0]

R/W

This register contains the eight MSBs of the 10-bit t1 time.

Table 75. Register 0xFE0D—PWM Rising Edge Setting (PWM Pin)

Bits

Bit Name

R/W

Description

[7:4]

RSVD

Reserved.

[3:2]

R/W

These bits contain the two LSBs of the 10-bit t1 time. This value is always used with the eight bits of

Modulate enable

R/W

1 = PWM modulation acts on the t1 edge.

0 = no PWM modulation of the t1 edge.

t1 sign

R/W

1 = positive sign. Increase of PWM modulation moves t1 right.

0 = negative sign. Increase of PWM modulation moves t1 left.
