High-Performance 8-Bit CMOS EPROM Microcontrollers

Microchip Technology 

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.
