Flexible Motor Control Pulse Width Modulator Module (FlexPWM)
1 = A logic 1 is supplied to the deadtime generator of submodule 0 instead of PWM23.
0 = A logic 0 is supplied to the deadtime generator of submodule 0 instead of PWM23.
OUT45_0 - Software Controlled Output 45_0
This bit is only used when SEL45 for submodule 0 is set to 0b10. It allows software control of which
signal is supplied to the deadtime generator of that submodule.
1 = A logic 1 is supplied to the deadtime generator of submodule 0 instead of PWM45.
0 = A logic 0 is supplied to the deadtime generator of submodule 0 instead of PWM45.

NOTE
The deadtime source select bits are double buffered and do not take effect
until a FORCE_OUT event occurs within the appropriate submodule. Refer
to Figure 25-17 to see how FORCE_OUT is generated. Reading these bits
reads the buffered value and not necessarily the value currently in effect.
SEL23_3 - PWM23_3 Control Select
This field selects possible over-rides to the generated PWM23 signal in submodule 3 that will be
passed to the deadtime logic upon the occurrence of a "Force Out" event in that submodule.
• 00 = Generated PWM23_3 signal is used by the deadtime logic.
• 01 = Inverted generated PWM23_3 signal is used by the deadtime logic.
• 10 = OUT23_3 bit is used by the deadtime logic.
• 11 = EXTA[3] signal is used by the deadtime logic.
SEL45_3 - PWM45_3 Control Select
This field selects possible over-rides to the generated PWM45 signal in submodule 3 that will be
passed to the deadtime logic upon the occurrence of a "Force Out" event in that submodule.
• 00 = Generated PWM45_3 signal is used by the deadtime logic.
• 01 = Inverted generated PWM45_3 signal is used by the deadtime logic.
• 10 = OUT45_3 bit is used by the deadtime logic.
• 11 = EXTB[3] signal is used by the deadtime logic.
SEL23_2 - PWM23_2 Control Select
This field selects possible over-rides to the generated PWM23 signal in submodule 2 that will be
passed to the deadtime logic upon the occurrence of a "Force Out" event in that submodule.
• 00 = Generated PWM23_2 signal is used by the deadtime logic.
