MOVE dst., #1 Set Bit
Description: Sets the bit specified by dst..
Status Flags: C, E (if dst is PSF)
Operation:
dst . ← 1
Encoding: 15 0
1ddd dddd 1bbb 0111
Example(s): ; M0[0] = 00h
MOVE M0[0] .1, #1 ; M0[0] = 02h
MOVE M0[0] .7, #1 ; M0[0] = 82h
Special Notes: Only system module 8 and peripheral modules (0 to 5) are supported by MOVE dst., #1 .
NEG Negate Accumulator
Description: Performs a negation (two’s complement) of the active accumulator and returns the result back to the
active accumulator .
Status Flags: S, Z
Operation:
Acc ← ~Acc + 1
Encoding: 15 0
1000 1010 1001 1010
Example(s): ; Acc = 0FEEDh, S=1, Z=0
NEG ; Acc = 0113h, S=0, Z=0
OR src Logical OR
Description: Performs a logical-OR between the active accumulator (Acc or A[AP]) and the specified src data .
For the complete list of src specifiers, reference the MOVE instruction . The PFX[n] register may be
used to supply the high byte of data for 8-bit sources .
Status Flags: S, Z
Operation:
Acc ← Acc OR src
Encoding: 15 0
f010 1010 ssss ssss
Example(s): ; Acc = 2345h for each example
OR A[3] ; A[3]= 0F0Fh → Acc = 2F4Fh
OR #1133h ; MOVE PFX[0], #11h (smart-prefixing)
; OR #33h
→ Acc = 3377h
Special Notes: The active accumulator (Acc) is not allowed as the src for this operation .
