When configured as general-purpose I/O signals, software can read inputs by reading the associated GPIO
data register (See

As well, a general purpose input register is loaded with the values of the local bus address/data pins at the
negation of HRESET. See

19.5.3
The MPC8544E has very little signal multiplexing. Two sets of DMA channel triggering signals can
alternately be placed on other signals as follows:
For details regarding the selection of the alternate function DMA trigger, see
Function Signal Multiplex Control Register (PMUXCR).”

LCS[5:7] are multiplexed with DMA channel 2 DMA_DREQ2, DMA_DACK2, and
DMA_DONE2.
IRQ[9:11] are multiplexed with DMA channel 3 DMA_DREQ3, DMA_DACK3, and
DMA_DDONE3.

Unused IRQn signals may also be used as general-purpose inputs. The
external interrupt summary register (ERQSR) can be used to monitor these
signals. See
