LAR
Load Auxiliary Register
7-80
Description
The contents of the specified data-memory address or an 8-bit or 16-bit
constant are loaded into the specified auxiliary register (ARx). The specified
constant is treated as an unsigned integer, regardless of the value of SXM.
The LAR and SAR (store auxiliary register) instructions can be used to load
and store the auxiliary registers during subroutine calls and interrupts. If an
auxiliary register is not being used for indirect addressing, LAR and SAR
enable the register to be used as an additional storage register, especially for
swapping values between data-memory locations without affecting the
contents of the accumulator.
