3.3.2. Command code
i) Load command code (0000h to 0010h)
Fig. 3.2. Timing chart for load command code execution
Enter the load command code as command code (RWwn+2), enter the parameter number as
necessary and turn the command code execution request (RY (n+2) 1) on to acquire the data
corresponding to the specified loading code in load data (RWrn+3, RWrn+4).
Obtained 32-bit data pieces are divided into the upper 16 bits and lower 16 bits when they are
stored in remote registers.
All data is in hexadecimals. At the time, command code execution completion (RX (n+2) 1) is
turned on simultaneously. Load data from (RWrn+3, RWrn+4) while the command code execution
request (RN (n+2) 1) remains turned on. The data is held until the next load command code is
entered and the command code execution request (RY (n+2) 1) is turned on.
If a command code not included in specifications is set as a command code (RWwn+2), an error
code (
1
) is set in the response code. If a parameter that cannot be used is loaded, an error
(
2
) is set.
Turn the command code execution request (RY (n+2) 1) off after data loading is finished.
