10.3.3 Drawing Control Registers
CSRW
The CSRW command sets the cursor address when indirect addressing is used. The values
from REG[1Ch] through REG[1Dh] are passed as parameters when the CSRW command
is issued. For further information on the CSRW command, see Section 11.1.10, “CSRW”
on page 78.
bits 15-0
Cursor Write (CSRW) bits [15:0]
These bits set the display memory address to the data at the cursor position as shown in
Figure 12-10 “Cursor Movement,” on page 88.
Note
The microprocessor cannot directly access the display memory in indirect addressing
mode.
For Indirect Addressing Mode:
The MREAD and MWRITE commands use the address in this register when in indirect
mode. 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 are from the last set address or the
address after previous automatic increments.
