- Lead Descriptions -
Data Bus: These leads are the bidirectional data bus used
for transferring data between the PHAST-12N and the host
processor.
MPD15 is the most significant bit.
Motorola notation: D[ ]
lead enables data transfers between the host processor and
the PHAST-12N through a read or write cycle.
Motorola notation: CS
(read or write) transfer between the host processor and the
PHAST-12N.
Motorola notation: DS
that the actual transfer between the host processor and the
PHAST-12N is a write transfer.
Motorola notation: R/W
Data Transfer Acknowledge: For a write access, an active
edge on this lead indicates that data is written to the
addressed memory location. For a read access, an active
edge on this lead indicates that the data to be read from the
addressed memory location is available on the data bus.
Active level depends on MPACKLEVEL.
Motorola notation: DSACK
Interrupt Request: This lead signals an interrupt request to
the host processor.
Active level depends on MPINTLEVEL.
