OPERATION MODES

Table-1 shows the function truth table for a listing of all available RAM ports and transfer

operation of MSM518122.

The RAM port and data transfer operations are determined by the state of

CAS

,

DT

/

OE

,

WB

/

WE

,

SE

and DSF at the falling edge of

RAS

and by the level of DSF at the falling edge of

CAS

.

Table-1. Function Truth Table

If the DSF is 'high" at the falling edge of

RAS

, special functions such as split transfer, flash write,

and load/read color register can be invoked. If the DSF is "low" at the falling edge of

RAS

and

"high" at the falling edge of

CAS

, the block write feature can be invoked.

If the DSF is "low" at the falling edge of

RAS

and

CAS

, only the conventional multiport DRAM

operating feature can be invoked.
