To implement indirect addressing, a file select register (FSR) and indirect register (INDF) are used.

Operation with WREG and indexed register.

The result can be written to either the Working register (e.g.

A register number is written to the FSR, after which reads from or writes to INDF will actually be to or from the register pointed to by FSR.

Until SSE2, SSE integer instructions introduced with later SSE extensions could still operate on 64 bit MMX registers because the new XMM registers require operating system support.

Pointers are implemented using a register pair after writing an address to the FSR (file select register), the INDF (indirect f) register becomes an alias for the addressed register.

In both cases, the upper address bits are provided by the PCLATH register.

Some operations, such as bit setting and testing, can be performed on any numbered register, but bi operand arithmetic operations always involve W (the accumulator), writing the result back to either W or the other operand register.

To load a constant, it is necessary to load it into W before it can be moved into another register.

Lookup tables are implemented using a computed codice_15 (assignment to PCL register) into a table of codice_17 instructions.

There are also eight one byte call instructions (RST) for subroutines located at the fixed addresses 00h, 08h, 10h...,38h.

)The PCLATH register supplies high order instruction address bits when the 8 bits supplied by a write to the PCL register, or the 11 bits supplied by a codice_15 or codice_14 instruction, is not sufficient to address the available ROM space.

The badge for the register is two crossed quills over a book encircled by the Garter surmounted by a crown.

Upstart Event Monitor

On the older cores, all register moves needed to pass through W, but this changed on the high end cores.

Arithmetic operations could therefore often have results as well as operands directly in memory (in addition to register or immediate).
