Type
Microprocessor Address Bus: 15-bit address bus
used by the Host Processor for accessing the
Envoy-CE2 for a read/write cycle. UPA14 is the
Most Significant Bit (MSB).
Microprocessor Data Bus: Bi-directional 16-bit
data bus used for transferring data between the
Envoy-CE2 and the Host Processor. UPD15 is the
Most Significant Bit (MSB).
Write/Transfer Start: In Intel Mode, this pin is used
for the Write signal and in Motorola mode, this pin is
used for the active low Transfer start signal.
Read/Write: In Intel Mode, this pin is used for the
Read signal and in Motorola mode, this pin controls
type of data transfer (Write = 0/Read = 1).
Interrupt: Active low level-based interrupt to Host
processor.
