MOVLR
Move Literal to high nibble in
BSR
Syntax:
[ label ] MOVLR k
Operands:
0  k  15
Operation:
k  (BSR<7:4>)
Status Affected: None
Encoding:
1011 101x kkkk uuuu
Description:
The 4-bit literal 'k' is loaded into the
most significant 4-bits of the Bank
Select Register (BSR). Only the high
4-bits of the Bank Select Register
are affected. The lower half of the
BSR is unchanged. The assembler
will encode the “u” fields as 0.
