Freescale Semiconductor Multiple Serial Interface 287
RDPS2 — Reduce Drive of Port S[7:4]
0 = Port S[7:4] output drivers operate normally
1 = Port S[7:4] output pins have reduced drive capability for lower
power and less noise
RDPS1 — Reduce Drive of Port S[3:2]
0 = Port S[3:2] output drivers operate normally
1 = Port S[3:2] output pins have reduced drive capability for lower
power and less noise
RDPS0 — Reduce Drive of Port S[1:0]
0 = Port S[1:0] output drivers operate normally
1 = Port S[1:0] output pins have reduced drive capability for lower
power and less noise
PUPS2 — Pull-up Port S[7:4] Enable
0 = No internal pull-ups on port S[7:4]
1 = Port S[7:4] input pins have an active pull-up device. If a pin is
programmed as output, the pull-up device becomes inactive.
PUPS1 — Pull-up Port S[3:2] Enable
0 = No internal pull-ups on port S[3:2]
1 = Port S[3:2] input pins have an active pull-up device. If a pin is
programmed as output, the pull-up device becomes inactive.
PUPS0 — Pull-up Port S[1:0] Enable
0 = No internal pull-ups on port S[1:0]
1 = Port S[1:0] input pins have an active pull-up device. If a pin is
programmed as output, the pull-up device becomes inactive.
