Note 1. Beginning word: 0000 to 0049 and 0200 to 0252 in CPM2A/CPM2C PCs,
0000 to 0019 and 0200 to 0252 in CPM1/CPM1A/SRM1(-V2) PCs.

Note Words 0050 to 0199 cannot be specified in CPM2A/CPM2C PCs and words
0020 to 0199 cannot be specified in CPM1/CPM1A/SRM1(-V2) PCs. If an at-
tempt is made to write to any of these words, the writing operation will not be
executed and normal completion occurs.
Write Data (Command)
Specify in order the contents of the number of words to be written to the IR or SR
area in hexadecimal, starting with the specified beginning word.
Note If data is specified for writing which exceeds the allowable range, an error will be
generated and the writing operation will not be executed. If, for example, 252 is
specified as the beginning word for writing,and two words of data are specified,
then 253 will become the last word for writing data, and the command will not be
executed because SR 253 is beyond the writable range.
Writes data to the LR area, starting from the specified word. Writing is done word
by word.
