PIC17C4X
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.
Words: 1
Cycles: 1
Q Cycle Activity:
Q1 Q2 Q3 Q4
Decode Read literal
'k:u'
Execute Write
literal 'k' to
BSR<7:4>
Example:
MOVLR 5
Before Instruction
BSR register = 0x22
After Instruction
BSR register = 0x52
Note: This instruction is not available in the
PIC17C42 device.
MOVLW Move Literal to WREG
Syntax: [
label ] MOVLW k
Operands: 0 ≤ k ≤ 255
Operation: k → (WREG)
Status Affected: None
Encoding:
1011 0000 kkkk kkkk
Description:
The eight bit literal 'k' is loaded into
WREG.
Words: 1
Cycles: 1
Q Cycle Activity:
Q1 Q2 Q3 Q4
Decode Read
literal 'k'
Execute Write to
WREG
Example:
MOVLW 0x5A
After Instruction
WREG = 0x5A
