Changing the I/O Table

The I/O Table Transfer operation transfers a copy of the I/O table to RAM
program memory.This allows the user program and I/O table to be written
into EPROM together.
Note When power is applied to a PC which has a copy of an I/O table stored in its
program memory, the I/O table of the CPU will be overwritten. Changes
made in the I/O table do not affect the copy of the I/O table in program mem-
ory; I/O Table Transfer must be repeated to change the copy in program
memory.
The I/O Table Transfer operation will not work if:
When the memory unit is not RAM, or
2. When the contents of program memory exceeds 31.7K words. (To find
out the capacity of program memory, do an instruction search for
END(01).)
I/O table transfer can only be done in PROGRAM mode.
Use of this operation allows I/O Units to be added or removed without the
need to re-register the I/O table or amend the user program. The I/O Table
The following indicates that the
I/O table cannot be transferred.
