Add W, the Carry flag and data memory
location âfâ. If âdâ is â0â, the result is
placed in W. If âdâ is â1â, the result is
placed in data memory location âfâ.
If âaâ is â0â, the Access Bank is selected.
If âaâ is â1â, the BSR is used to select the
GPR bank (default).
If âaâ is â0â and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f ⤠95 (5Fh). See
Section 26.2.3 âByte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Modeâ for details.
