Clear Function (see Figure „Control Word Data Definition“
(page 13) and Table „Clear Function“ (page 13))
Control Word bit, D7 clears the character RAM to 20 hex and the
flash RAM to all zeroes. The RAMs are cleared within three clock
cycles (110 µs minimum, using the internal clock) when D7 is set
to 1. During the clear time the display must not be accessed.
When the clear function is finished, bit 7 of the Control Word RAM
will be reset to a “0”.

Reset Function
The display should be reset on power up of the display
(RST=LOW). When the display is reset, the Character RAM, Flash
RAM, and Control Word Register are cleared.
The display's internal counters are reset. Reset cycle takes three
clock cycles (110 µs minimum using the internal clock). The dis-
play must not be accessed during this time.
To synchronize the flashing and blinking of multiple displays, it is
necessary for the display to use a common clock source and reset
all the displays at the same time to start the internal counters at
the same place.
While RST is low, the display must not be accessed by RD nor
WR.
