Function
Converts hexadecimal digits from the
source word (S) into 8-bit ASCII values,
starting at leftmost or rightmost half of the
starting destination word (D). The right-
most digit of Di designates the first source
digit. The next digit to the left gives the
number of digits to be converted. The next
digit specifies the whether the data is to be
transferred to the rightmost (0) or leftmost
(1) half of the first destination word. The
leftmost digit specifies parity:
0: none,
1: even, or
2: odd.

Controls programmed (scheduled) inter-
rupts and interrupts from Interrupt Input
Units. Each PC can have up to 4 IIUs. N de-
fines the source of the interrupt: 000 to 003
designate the no. of the IIU; 004 desig-
nates a scheduled interrupt. In IIUs, bits 00
to 07 identify the interrupting subroutine,
higher bits are not used. Bit 00 of Unit 0 cor-
responds to interrupt subroutine 00,
through to bit 07 of Unit 3 which corre-
sponds 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
000 Masks and unmasks in-
terrupt bits for the desig-
nated Unit (N) according
to the data in D. Bits cor-
responding to ON bits in
D are masked, those cor-
responding to OFF bits
are unmasked. Masked
bits are recorded and will
be executed when they
are unmasked (unless
previously cleared).
001 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
executed when the bit is
unmasked.
002 Copies the mask status of
the designated IIU to D.
