Extension I/O verify
error unit
When the state of installation of FP-X0
expansion I/O unit has changed since the
power was turned on, the bit corresponding to
the unit No. will turn on. Monitor using binary
DT90014
Operation auxiliary
register for data shift
instruction
One shift-out hexadecimal digit is stored in bit
positions 0 to 3 when the data shift instruction,
F105 (BSR) or F106 (BSL) is executed. The
value can be read and written by executing F0
(MV) instruction.

DT90015
Operation auxiliary
register for division
instruction
The divided remainder (16-bit) is stored in
DT90015 when the division instruction F32(%)
or F52(B%) instruction is executed. The
divided remainder (32-bit) is stored in
DT90015 and DT90016 when the division
instruction F33(D%) or F53(DB%) is executed.
The value can be read and written by
executing F0(MV) instruction.
