Example(s): MOVE A[0], A[3] ; A[0] ← A[3]
MOVE DP[0], #110h ; DP[0] ← #0110h (PFX[0] register used)
; MOVE PFX[0], #01h (smart-prefixing)
; MOVE DP[0], #10h
MOVE DP[0], #80h ; DP[0] ← #0080h (PFX[0] register not needed)
Special Notes: Proper loading of the PFX[n] registers, when for the purpose of supplying 16-bit immediate data or accessing 2-cycle
destinations, is handled automatically by the assembler and is therefore an optional step for the user when writing
assembly source code. Examples of the automatic PFX[n] code insertion by the assembler are demonstrated below.

MOVE DP[0], #0100h MOVE PFX[0], #01h

MOVE Acc., C Move Carry Flag to Accumulator Bit
Description: Replaces the specified bit of the active accumulator with the Carry bit.
Status Flags: S, Z
Operation: Acc. ← C
Encoding: 15 0
MAXQ010
Example(s):
; Acc = 80h, S=1, Z=0, C=0
MOVE Acc.7, C ; Acc = 00h, S=0, Z=1
MAXQ020
Example(s):
; Acc = 8000h, S=1, Z=0, C=0
MOVE Acc.15, C ; Acc = 0000h, S=0, Z=1
Special Notes: For the MAXQ10, the accumulator width is only 8 bits. Thus, only bit index encoding ('bbbb') for bits 0 ('0000')
through 7 ('0111') is supported.
