D
READ(88) reads data from memory area of
an Special I/O Unit and transfers it through
word (S) allocated to the Special I/O Unit to
destination words (D gives the address of
the first destination word). N is the number
of words to be transferred. The EQ Flag is
set when the transfer is completed.

INTERRUPT

(@)INT(89)
INT(89)
CC
N
D
Controls programmed (scheduled)
interrupts and interrupts from Interrupt
Input Units. Each PC can have up to 4 IIUs.
N defines the source of the interrupt: 000 to
003 designate the no. of the IIU; 004
designates a scheduled interrupt. In IIUs,
bits 00 to 07 identify the interrupting
subroutine, higher bits are not used. Bit 00
of Unit 0 corresponds to interrupt
subroutine 00, through to bit 07 of Unit 3
which corresponds to subroutine 31. CC is
the control code, the meaning of which
depends on the value of N, as follows:
CC N = 000 to 003 N = 004
000

Masks and unmasks in-
terrupt bits for the desig-
nated Unit (N) according
to the data in D. Bits corre-
sponding to ON bits in D
are masked, those corre-
sponding to OFF bits are
unmasked. Masked bits
are recorded and will be
executed when they are
unmasked (unless pre-
viously cleared).
Clears the masked inter-
rupt bits of the designated
Unit (N) according to the
corresponding ON bits in
D. The subroutines corre-
sponding to bits cleared in
this manner will not be ex-
ecuted when the bit is un-
masked.
Copies the mask status of
the designated IIU to D.
The interrupt time
interval is set ac-
cording to the data
in D (00.01 to
99.99 s) The deci-
mal point is not en-
tered. The inter-
rupt is cancelled if
D is 00.00.
The time to the
first interrupt is set
according to the
data in D (00.01 to
99.99 s) The deci-
mal point is not en-
tered. The inter-
rupt is cancelled if
D is 00.00.
Copies the time in-
terval data to D.
