Procedures from Powering ON to Display Start
The procedures from powering ON to Display Start are as follows:

5.
Instruction Execution Time
Any instructions other than the DISPLAY CLEAR are completed within the cycle time (tcyc) represented with the instruction
input timing characteristics. For instance, when the instruction input cycle time is 500
μ
sec, the instruction can be completed
within 500
μ
sec. Consequently, instructions can be input in succession without confirming the BUSY flag. Also, load to the
MPU and the current consumption can be drastically reduced. Inputting the next command within the cycle time is
prohibited.
In the DISPLAY CLEAR mode, it is necessary to write a space code in all of DDRAMs. For the write execution time, refer to
page 18,
Instruction Explanation
of this specification.
6.
Read and Write Display Data from and In MPU
The Display Data is accessed from the MPU to DDRAM, CGRAM, ICONRAM or ICON BLINK RAM by executing the READ
or WRITE command following the ADDRESS SETTING command of individual RAMs. Always execute the ADDRESS
SETTING command before executing the READ command. When the ADDRESS SETTING command is not executed,
correct display data cannot be read. After executing the READ or WRITE command, the column address is incremented or
decremented depending upon the value of the ID of the ENTRY MODE Setting. Consequently, when the cycle time
