The SLD instruction uses indirect addressing to load data from the data space to the
TPI physical layer shift-register for serial read-out. The data space location is
pointed by the Pointer Register (PR), where the address must have been stored before
data is accessed. The Pointer Register is either left unchanged by the operation, or
post-incremented.
Table 21-2. The Serial Load from Data
Space (SLD) Instruction| Operation | Opcode | Remarks | Register |
|---|
| data ← DS[PR] | 0010 0000 | PR ← PR | Unchanged |
| data ← DS[PR] | 0010 0100 | PR ← PR + 1 | Post increment |
