0  f  255

a  [0,1]

(f)+1f

0110 110a ffff ffff

Location ‘f’ is negated using two’s

complement. The result is placed in the

data memory location ‘f’.

If ‘a’ is ‘0’, the Access Bank is selected.

If ‘a’ is ‘1’, the BSR is used to select the

GPR bank.

If ‘a’ is ‘0’ and the extended instruction

set is enabled, this instruction operates

in Indexed Literal Offset Addressing

mode whenever f 95 (5Fh). See

Section 25.2.3 “Byte-Oriented and

Bit-Oriented Instructions in Indexed

Literal Offset Mode” for details.
