Data Areas
Appendix E
330
Dedicated Bits
Most of the bits in the SR and AR area are dedicated for specific purposes. These are summarized in the fol-
lowing tables. Refer to 3-4 SR Area and 3-5 AR Area for details.
SR Allocations
As a rule, SR area bits can be used only for the purposes for which they are dedicated. The SR area contains
flags and control bits used for monitoring PC operation, accessing clock pulses, and signalling errors. SR area
word addresses range from 236 through 255; bit addresses, from 23600 through 25507.
