Function
Microprocessor Write Enable (Intel Bus
Mode)
This signal is driven by the bus master to
indicate a write data transfer
Read/Write Enable (Motorola Bus Mode)
This three-state signal is driven by the bus
master to indicate the direction of the bus’s
data transfer
Microprocessor Read Enable (Intel Bus
Mode)
This signal is driven by the bus master to
indicate a read data transfer
Microprocessor Transfer Start (Motorola
Bus Mode)
This signal is asserted by the bus master to
indicate the start of a bus cycle that
transfers data to or from the device
Microprocessor Ready (Intel Bus Mode)
This three-state output indicates that the
device has accepted date from the master
(write) or has driven the data bus with valid
data (read)
Microprocessor Transfer Acknowledge
(Motorola Bus Mode)
This three-state output indicates that the
device has accepted date from the master
(write) or has driven the data bus with valid
data (read)
Microprocessor Interrupt Request 1
Main interrupt pin indicating a special event
in the IWE8.
Microprocessor Interrupt Request 2
This signal is generated by timer set 2 to
indicate that a counter expired
