Preliminary Data Sheet
External Slave Peripheral Interface
DMAAck0:3
Used by the PPC440GRx to indicate that data transfers have
occurred.
O3.3V LVTTL
1
DMAReq0
Used by slave peripherals to indicate they are prepared to
transfer data.
I
3.3V LVTTL
1
DMAReq1
Used by slave peripherals to indicate they are prepared to
transfer data.
I
3.3VLVTTL
1, 5
DMAReq2:3
Used by slave peripherals to indicate they are prepared to
transfer data.
I
3.3VLVTTL
1
EOT0:3/TC0:3
End Of Transfer/Terminal Count.
I/O
3.3V LVTTL
1
PerAddr02:07
Peripheral address bus used by the PPC440GRx when not in
external master mode; otherwise, used by external master.
I/O
3.3V LVTTL
1, 2
PerAddr08:31
Peripheral address bus used by the PPC440GRx when not in
external master mode; otherwise, used by external master.
I/O
3.3V LVTTL
PerData00:31
Peripheral data bus used by the PPC440GRx when not in
external master mode; otherwise, used by external master.
Note: PerData00 is the most significant bit (msb) on this bus.
I/O
3.3V LVTTL
PerDataPar0:3
Peripheral data bus parity used by the PPC440GRx when not
in external master mode; otherwise, used by external master.
I/O
3.3V LVTTL
PerBLast
Used by either the peripheral controller, DMA controller, or
external master to indicates the last transfer of a memory
access.
I/O
3.3V LVTTL
1, 4
PerCS0
External peripheral device select.
O
3.3V LVTTL
2
PerCS1:5
External peripheral device select.
I/O
3.3V LVTTL
1, 2
PerOE
Used by either peripheral controller or DMA controller
depending upon the type of transfer involved. When the
PPC440GRx is the bus master, it enables the selected device
to drive the bus.
O
3.3V LVTTL
1, 2
PerReady
Used by a peripheral slave to indicate it is ready to transfer
data.
I3.3V LVTTL
1
PerR/W
Used by the PPC440GRx when not in external master mode,
as output by either the peripheral controller or DMA controller
depending upon the type of transfer involved. High indicates a
read from memory, low indicates a write to memory.
Otherwise, it is used by the external master as an input to
indicate the direction of transfer.
I/O
3.3V LVTTL
1, 2
PerWBE0:3
External peripheral data bus byte enables.
I/O
3.3V LVTTL
1, 2
PerErr
External Error. Used as an input to record external slave
peripheral errors.
I3.3V LVTTL
