Subroutine 0 is called and
executed regardless of the
status of the input condition.
The logic results of a, b, c is
stored in A000.00 as the input
condition. The actual memory
address of D00000 (10000 hex)
is stored in IR0 and the actual
memory address of D00100
(10064 hex) is stored in IR1
Either ACC or INI is executed
depending on the staus of
A000.00. If ACC is executed, the
parameters (e.g., rate of
acceleration) starting at D00000
are accessed using the actual
memory address stored in IR0 to
execute acceleration.
