RDPP — Reduced Drive of Port P
PUPP — Pull-Up Port P Enable
PSBCK — PWM Stops while in Background Mode
Read anytime but write only in special mode (SMODN = 0). These bits
are available only in special mode and are reset in normal mode.
DISCR — Disable Reset of Channel Counter on Write to Channel
Counter
DISCP — Disable Compare Count Period
DISCAL — Disable Load of Scale-Counters on Write to the Associated
Scale-Registers
0 = All port P output pins have normal drive capability.
1 = All port P output pins have reduced drive capability.
0 = All port P pins have an active pull-up device disabled.
1 = All port P pins have an active pull-up device enabled.
0 = Allows PWM to continue while in background mode.
1 = Disable PWM input clock when the part is in background mode.
0 = Normal operation. Write to PWM channel counter will reset
1 = Write to PWM channel counter does not reset channel counter.
0 = Normal operation
1 = In left-aligned output mode, match of period does not reset the
0 = Normal operation
1 = Write to PWSCAL0 and PWSCAL1 does not load scale
