Instruction Set
SLD - Serial LoaD from data space using indirect addressing
The TPI has a compact instruction set that is used to access the TPI Control and Status Space
(CSS) and the data space. The instructions allow the external programmer to access the TPI,
the NVM Controller and the NVM memories. All instructions except SKEY require one byte oper-
and following the instruction. The SKEY instruction is followed by 8 data bytes. All instructions
are byte-sized.
The TPI instruction set is summarised in
Table 14-1.
The SLD instruction uses indirect addressing to load data from the data space to the TPI physi-
cal 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, as shown in
Table 14-2.
