Notes:
1. In general, the internal registers of the SED1330F/1335F/1336F 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 one 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.
