Note: 1.
Line increment
M and N are addresses, M is in line units, N is units of 32 dots,
and m and n are in line and dot units respectively.
Clear (independent functions for read and write)
The clear function both resets the address pointer to 0 without regard for the value on
WRS
,
WAS
,
WLRS
,
WWND
,
RRS
,
RAS
,
RLRS
and
RWND
, and if window mode is set, clears window mode.
Clear Operation:
When clock gate signal (
CGW
,
CGR
) is low, the clear operation can be executed on
any cycle by setting the
RCLR
pin low for read and the
WCLR
pin low for write. When the interval
conditions listed in Notes on usage 7 to 10 are met, clear operation is executed at any time without regard
of the level on
WE
and
OE
. (See ‘Notes on usage’ 14 and 15 on the operation when clock gate signal
(
CGW
,
CGR
) is high)
Access of New and Previous Data
New data access (follow-up read out of data currently being written):
Written data can be read out 160
WCK cycles after it is written. However, it is necessary to execute the read jump address setup operation
outside the time period between 32 WCK cycles before write to that address is started and 32 WCK cycles
after write to that address is completed.
