Register Description - PDI Instruction and Addressing Registers
Instruction Register
Pointer Register
Figure 22-10. PDI instruction set summary
These registers are all internal registers that are involved in instruction decoding or PDIBUS
addressing. None of these registers are accessible as register in a register space.
When an instruction is successfully shifted into the physical layer shift-register, it is copied into
the Instruction Register. The instruction is retained until another instruction is loaded. The rea-
son for this is that the REPEAT command may force the same instruction to be run repeatedly
requiring command decoding to be performed several times on the same instruction.
The Pointer Register is used to store an address value specifying locations within the PDIBUS
address space. During direct data access, the Pointer Register is updated by the specified num-
ber of address bytes given as operand bytes to the instruction. During indirect data access,
addressing is based on an address already stored in the Pointer Register prior to the access
