Microprocessor Data Bus: Bi-directional 16-bit data
bus used for transferring data between the Envoy-
CE4 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.
Synchronization Input Pulse: Global input signal
that occurs every 10 SMIIREFCLK clock cycles and
marks the start of data segments.
Synchronization Pulse Direction: Determines the
source of the synchronization pulse.
0 - The synchronization pulse will be taken from an
internally generated source
1 - The synchronization pulse to the 8 SMII ports will
be taken from SSYNCIN
