S1D13305 Series
Technical Manual
The cursor address register can only be modified by the
CSRW command, and by the automatic increment after
an MREAD or MWRITE command. It is not affected by
display scrolling.
If a new address is not set, display memory accesses will
be from the last set address or the address after previous
automatic increments.
8.4.2. CSRR
Reads from the cursor address register. After issuing the
command, the data read address is read twice, for the low
byte and then the high byte of the register.
8.5. Memory Control Commands
8.5.1. MWRITE
The microprocessor may write a sequence of data bytes
to display memory by issuing the MREAD command and
then writing the bytes to the S1D13305 series. There is no
need for further MWRITE commands or for the micro-
