Notes:
1. In general, the internal registers of the RA8835 series 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-byte parameters (where two bytes are treated as 1 data item) are handled as follows:
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.
