Table E.2
1. Scratch Pad registers reside physically within the Controller module.
2. LP_status[i] = 1 if Loop control register LPi = 0.
3. Acc_status[2] = 1 if C accumulator < 0, Acc_status[1] = 1 if C accumulator >= 0, Acc_status[0] = 1 if
4. This register is mapped from Group 5 into Controller scratchpad memory space so as to be readable
5. The microcode assembler checks for accesses to unmapped addresses and writes to read-only
6. This register resides physically within the Controller module.
7. Registers 81-85 reside physically within the Controller module.
