Special I/O
Unit Initializ-
ing Flags
These flags are ON while the corre-
sponding Special I/O Unit is initializ-
ing after its Special I/O Unit Restart
Bit (A502.00 to A507.15) is turned
ON or the power is turned ON.
The bits in these words correspond
to unit numbers 0 to 95 as follows:
A330.00 to A330.15: Units 0 to 15
A331.00 to A331.15: Units 16 to 31
----
A335.00 to A335.15: Units 80 to 95
Use these flags in the program to
prevent the Special I/O Unit’s refresh
data from being used while the Unit
is initializing. Also, IORF(097) cannot
be executed while a Special I/O Unit
is initializing.
These bits are turned OFF automati-
cally when initialization is completed.
OFF: Not ini-
tializing
ON: Initializ-
ing
(Reset to 0
automatically
after initializa-
tion.)
