Signal Name
Peripheral address bus.
Note:
External peripheral data bus byte enable.
Used by the peripheral controller to indicates the last
transfer of a memory access.
External peripheral device select.
Peripheral data bus.
Note:
Used by peripheral controller or DMA controller
depending upon the type of transfer involved. When the
PPC440SPe is the bus master, it enables the selected
device to drive the bus.
External peripheral data bus byte parity.
Used by a peripheral slave to indicate it is ready to
transfer data.
The peripheral controller set this signal to High for a
Read from external memory, and to Low for a Write.
Write Enable.
Peripheral clock used by synchronous peripheral slaves.
External error used as an input to record external slave
peripheral errors.
IIC0 Serial Clock.
IIC0 Serial Data.
IIC1 Serial Clock.
IIC1 Serial Data.
PerAddr00 is the most significant bit (msb).
PerData0 is the most significant bit (msb).
