A14
This command is used to write the cursor address to the cursor register. Because the S1D13700
has only one address input bit, only two addresses in the address space of the MPU can be
specified at a time. Therefore, the MPU cannot directly access display memory. To compensate
for this inconvenience, the S1D13700 has a 16-bit cursor register that serves the purpose of
MPU addresses.
A14
The cursor address is set in the S1D13700 before display memory (VRAM, CG RAM, or CG
ROM) is automatically accessed. If this address is not set, display starts from the address set last
or an automatically shifted address. (The cursor address register can only be modified by other
than the CSRW command by executing a memory control command.)
The cursor address is not affected by scrolling display because it is managed by the absolute
display memory addresses fixed in hardware. Note also that the cursor address points to the
absolute display memory address where data for the origin part of the character field is stored.
This command is used to read a cursor address from the cursor register.When this command is
written to the S1D13700, the low-order byte of the cursor address (CSRL) is set in the output
buffer. Therefore, the high-order byte of the cursor address (CSRH) also can be read out by
entering the RD signal following this command.
