Note:
1. In general, the internal registers of the RA8835 are modified as each command parameter
is input. However, the microprocessor does not have to set all the parameters of a
command and may send a new command before all parameters have been input. The
internal registers for the parameters that have been input will have been changed but the
remaining parameter registers are unchanged.
2 bytes parameters( where two bytes are treated as 1 data item) are handled as following:
a. CSRW, CSRR: Each byte is processed individually. The microprocessor may read or
write just the low byte of the cursor address.
b. SYSTEM SET, SCROLL, CGRAM ADR. : Both parameter bytes are processed together.
If the command is changed after half of the parameter has been input, the single byte is
ignored.
2. APL and APH are 2-byte parameters, but are treated as two 1-byte parameters.
3. Please refer to RA8835 LCD Controller Data Book for detail.
