Mnemonic
There is 1 ISA bus read strobe and 1
ISA bus write strobe. They allow
connection of one independent ISA
bus peripherals, e.g. an IDE slave
device.
ISA bus wait line - available for both
busses
Enables peripherals at programmed
addresses.
CS[0] provides boot ROM selection
Two programmable buffer enables
allow seamless steering of external
buffers to split data and address bus in
sections.
Transfer Acknowledge signal
Wake-up signal input
Clock signal for Dual I
operation
Serial data port for second I
operation
Signal is receive serial data input for
DUART
Signal is transmit serial data output for
DUART
DUART signals a ready to receive
data query
Signals to DUART that data can be
transmitted to peripheral
Capable of output waveform or pulse
generation
