These flags are ON while the corresponding CPU Bus
Unit is initializing after its CPU Bus Unit Restart Bit
(A50100 to A50115) is turned from OFF to ON or the
power is turned ON.
Bits 00 to 15 correspond to unit numbers 0 to 15.
Use these flags in the program to prevent the CPU
Bus Unit's refresh data from being used while the Unit
is initializing. IORF(097) cannot be executed while an
CPU Bus Unit is initializing.
0: Not initializing
1: Initializing
(Reset to 0 automatically after initialization.)
These bits are turned OFF automatically when initial-
ization is completed.
These flags are ON while the corresponding Special
I/O Unit is initializing after its Special I/O Unit Restart
Bit (A50200 to A50715) is turned from OFF to ON or
the power is turned ON.
The bits in these words correspond to unit numbers 0
to 95 as follows:
A33000 to A33015: Units 0 to 15
A33100 to A33115: Units 16 to 31
----
A33500 to A33515: 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.
0: Not initializing
1: Initializing
(Reset to 0 automatically after initialization.)
These bits are turned OFF automatically when initial-
ization is completed.
These words contain the maximum value of the differ-
entiation flag numbers being used by differentiation
instructions.
