PWM AND PWM2 TIMING REGISTERS
Register 0xFE0C through Register 0xFE13 configure the rising and falling edges of the PWM outputs.
Table 74. Register 0xFE0C—PWM Rising Edge Timing (PWM Pin)
Bits
Bit Name
R/W
Description
[7:0]
t1
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
R
Reserved.
[3:2]
t1
R/W
These bits contain the two LSBs of the 10-bit t1 time. This value is always used with the eight bits of
Register 0xFE0C, which contains the eight MSBs of the t1 time.
1
Modulate enable
R/W
1 = PWM modulation acts on the t1 edge.
0 = no PWM modulation of the t1 edge.
0
t1 sign
R/W
1 = positive sign. Increase of PWM modulation moves t1 right.
0 = negative sign. Increase of PWM modulation moves t1 left.

Bits
Bit Name
R/W
Description
[7:0]
t2
R/W
This register contains the eight MSBs of the 10-bit t2 time.

t2
R/W
These bits contain the two LSBs of the 10-bit t2 time. This value is always used with the eight bits of
Register 0xFE0E, which contains the eight MSBs of the t2 time.
1
Modulate enable
R/W
1 = PWM modulation acts on the t2 edge.
0 = no PWM modulation of the t2 edge.
0
t2 sign
R/W
1 = positive sign. Increase of PWM modulation moves t2 right.
0 = negative sign. Increase of PWM modulation moves t2 left.
