Acknowledge (SPP mode). ACK# is asserted (low) by the
peripheral to indicate that a successful data transfer has taken
place.
Paper Empty. Activated by printer when it runs out of paper.
Busy (SPP mode). BUSY is asserted (high) by the peripheral when
it is not ready to accept data
Select (SPP mode). Asserted by host to select the peripheral
Peripheral selected. Asserted by peripheral when selected.
Error. Held low by the peripheral during an error condition.
Initialize (SPP mode). Commands the peripheral to initialize.
Auto Feed (SPP mode, open-drain)
Strobe (SPP mode). Used by peripheral to latch data currently
available on PD[7:0]
Parallel data bus
EEPROM clock
EEPROM active-high Chip Select
EEPROM data in. When the serial EEPROM is connected, this pin
should be pulled up using 1-10k resistor. When the EEPROM is
not used the internal pullup is sufficient.
EEPROM data out.
Crystal oscillator input
Crystal oscillator output. Maximum frequency 60MHz
Buffered crystal clock output. This clock can drive TTL clock
signals from a clock generator circuit connected at XTLI & XTLO.
Can be enabled/disabled by software.
Buffered PCI clock. Can be enabled/disabled by software
Mode selector:
00: 8-bit local bus
01: Parallel port
11: 32-bit local bus
