PowerPC 405GP Embedded Processor Data Sheet
40
PerOE
Used by either peripheral controller or DMA controller depending
upon the type of transfer involved. When the PPC405GP is the
bus master, it enables the selected SDRAMs to drive the bus.
O
5V tolerant
3.3V LVTTL
2
PerR/W
Used by the PPC405GP 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 used by the external master as an input to indicate
the direction of transfer.
I/O
5V tolerant
1, 2
PerReady
Used by a peripheral slave to indicate it is ready to transfer data.
I
5V tolerant
Rcvr
1, 2
PerBLast
Used by the PPC405GP when not in external master mode,
otherwise used by external master. Indicates the last transfer of a
memory access.
I/O
5V tolerant
3.3V LVTTL
1, 4
DMAReq0
DMAReq1
DMAReq2
DMAReq3
DMAReq0:3 are used by slave peripherals to indicate they are
prepared to transfer data.
I
5V tolerant
Rcvr
1, 5
DMAAck0
DMAAck1
DMAAck2
DMAAck3
DMAAck0:3 are used by the PPC405GP to indicate that data
transfers have occurred.
O
5V tolerant
3.3V LVTTL

Signal Functional Description (Part 8 of 12)
Multiplexed signals are shown in brackets following the first signal name assigned to each multiplexed ball.
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3k
to 3.3V, 10k to 5V)
3. Must pull down (recommended value is 1k
)
4. If not used, must pull up (recommended value is 3k
to 3.3V)
5. If not used, must pull down (recommended value is 1k
)
6. Strapping input during reset; pull-up or pull-down required
