Functional Description
(Continued)
OFF PHASE
In the OFF phase, both Master and Slave MPL transmitters
are turned off with zero current flowing on the MC and MD
lines.
Figure 7
shows the transition of the MPL bus into the
OFF phase. If an MPL line is driven to a logical Low (high
current) when the OFF phase is entered it may temporarily
pass through as a logical High (low current) before reaching
the zero line current state.
The link may be powered down by asserting both the Mas-
ter’s and Slaves’s PD* input pins (Low). This causes the
devices to immediately put the link to the OFF Phase and
internally enter a low power state. To avoid loss of data the
Master’s PD* input should only be asserted after the MPL
bus has been in the IDLE state for at least 20 MC clock
cycles. This gives the Slave enough time to complete any
write operations received from the MPL bus.
CPU INTERFACE COMPATIBILITY
The CPU Interface mode provides compatibility between a
CPU Interface and a small form factor (SFF) Display or other
fixed I/O port application. Two options are allowed:

Mode

Description
m68 Interface
(E, R/W*), 16-bit support
i80 Interface
(WR*, RD*), 16-bit support
1
It is not required that both the Master and the Slave to be
configured in the same mode. For example the Master may
be configured as an 80xx (i80) interface while the Slave is
configured for an 68xx (m68) interface.
Control information is carried over both MD lines. MD0 car-
ries the D0–7 data bits while MD1 the D8–15 data bits. See
Figure 8
