Compares the contents of data
memory location ‘f’ to the contents
of the W by performing an
unsigned subtraction.
If the contents of ‘f’ are greater than
the contents of WREG
fetched instruction is discarded and
a NOP is executed instead, making
this a two-cycle instruction. If ‘a’ is
0, the Access Bank will be
selected, overriding the BSR value.
If ‘a’ = 1, then the bank will be
selected as per the BSR value
(default).
