13.8
The 2 Phase PWM module may be configured to oper-
ate in a Complementary Output mode where PH1 and
PH2 are always 180 degrees out-of-phase (see
Figure 13-8). Three complementary modes are avail-
able and are selected by the COMOD<1:0> bits in the
PWMCON1 register (see Register 13-5). The differ-
ence between the modes is the method by which the
PH1 and PH2 outputs switch from the active to the
inactive state during the PWM period.

The Complementary Output mode facilitates driving
series connected MOSFET drivers by providing over-
lap or deadband drive timing between each phase out-
put (see Figure 13-9). Overlap or deadband times are
selectable by the CMDLY<4:0> bits of the PWMCON1
register. Delays from 0 to 155 nanoseconds (typical)
with a resolution of 5 nanoseconds (typical) are avail-
able.
Selection between overlap or deadband delay is con-
trolled by the OVRLP bit of the PWM control register
(PWMCON1<7>).
