TRUE to execute the upper and lower limit clipping function.
FALSE to turn the upper limit clipping flag (Xn1) and the lower limit clipping
flag (Xn2) to FALSE.
Status flags are allocated to the CPU's input area (WX).
The I/O addresses in the table show offset addresses. I/O addresses actu-
ally allocated are based on the first word number allocated to the unit.
Example: If the first word number is 10, the address number for the error
flag on channel 0 will be X100.
