Description
PCMCIAEn
Output EBI
This signal informs EBI that
PCMCIA Host Bus Adapter
wants to transfer data.
nPCMCIAOutEn[1:0] Output EBI
This signal informs EBI that
current cycle is a write cycle
and also indicates the write
byte size.
nPCMCIAOutLEn
Output EBI
EBI output data latch enable
signal
nPCMCIAInEn
Output EBI
This signal informs the EBI
that current cycle is read
cycle.
nPCMCIAInLEn[3:0] Output EBI
EBI Address Latch enable
signal
nPCMCIALatch
Output EBI
Address Latch enable signal
PCMCIAByteSeq[1:0] Output EBI
Control s the data sequence
byte lane
SELECTEDBA[6:0]
Output EBI
These bits are multiplexed
with BA [25:21,1:0] at EBI
