In general, the internal registers of the SED1335F 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 SED1335F LCD Controller Data Book for detail. AZ Displays, Inc. Page 09 AZ Displays, Inc.
