Because more than one signal is often multiplexed to one pin, each line in the signal name column is a separate function. For all MPC5554 I/O
pins the selection of the primary pin function, alternate function, or GPIO is determined in the SIU_PCR registers.
2
Each line in the signal name column corresponds to a separate signal function on the pin. For all device I/O pins, the primary, alternate, or GPIO
signal functions are designated in the PA field of the system integration unit (SIU) PCR registers except where explicitly noted.

V
DDE
(fast I/O) and V
DDEH
(slow I/O) power supply inputs are grouped into segments. Each segment of V
DDEH
pins can connect to a separate
3.3–5.0 V ( 5%/–10%) power supply input. Each segment of V
DDE
pins can connect to a separate 1.8–3.3 V ( 10%) power supply, with the
exception of the V
DDE2
and V
DDE3
segments that are shorted together and must use the same power supply input. This segment is labelled V
DDE2
in the BGA map.
Refer to Tab le 2 -3 for a definition of the I/O pins that are powered by each segment.
