Operation: Src is moved into dest. Z will be set if the result is 0; otherwise, Z will be cleared. W is left holding the
source value in command number 2, 3, 4, 18, 20, 21 and 23. C will be cleared if an underflow occurred;
otherwise, C will be set to 1 in command number 7, 10 and 11. DC will be cleared if an underflow
occurred in the lowest nibble; otherwise, DC will be set in command number 7. The value of C will be
shifted into the LSB or MSB of W in command #10 and #11, respectively. C will be set to the previous
MSB or LSB of fr in command #10 and #11 respectively. Command #12 moves the nibble-swapped value
of fr into w. Instructions #6 through #12 are similar to NOT, SUB, INC, DEC, RL, RR and SWAP
instructions, respectively, but have the additional feature of moving the result to W. Only 4 bits are
affected by #17; use #13 followed by #16 to affect 5 bits in the SX48/52. If CARRYX is specified, c affects the result
of command #7. Insert an STC before command #7 to avoid strange results.
