Commands
Ranges for Start Address and Number of Bytes
The following table shows the commands and available designation range for specifying start
addresses and number of bytes in commands. If a value outside the available range is specified, a
command error will occur.
* If the start address is 20h and the number of bytes is 70h, the result is A + B = 90h, which gives a
command error.
