ACK#
INTR#
PE
Acknowledge Signal in SPP mode. ACK#is asserted (low)
by the peripheral to indicate that a successful data transfer
has taken place.
INTR#pin in EPP mode. Function identical to ACK#.
Paper Empty.
Activated by printer when it runs out of paper.
Busy Signal in SPP mode. BUSY is asserted (high) by the
peripheral when it is not ready to accept data
Wait signal in EPP mode.
Handshake signal for interlocked IEEE 1284 compliant EPP
cycles.
Select signal in SPP mode. Asserted by host to select the
peripheral.
Address strobe in EPP mode. Provides address read and
write strobe.
Peripheral selected.
Asserted by peripheral when selected.
Error.
Held low by the peripheral during an error condition.
Initialize signal in SPP mode. Commands the peripheral to
initialize.
Initialize signal in EPP mode. Function identical to SPP.
Auto Feed signal in SPP mode.
Data strobe signal in EPP mode. Provides data read and
write strobe.
Strobe signal in SPP mode. Used by the peripheral to latch
data currently available on the PD[7:0] lines.
Write signal in EPP mode. Indicates a write cycle when low
and a read cycle when high.
Parallel port bi-directional data bus

LOCAL_TRANS_EN
Parallel Port Data Output Enable.
This pin can be used by external transceivers. It is high when
PD[7:0] are in output mode, and low when they are in input
mode.
