ADD
Operation: src is added into dest. C will be set if an overflow occurs; otherwise, C will be cleared. DC will be set if
ADDB
Operation: src_bit is added into dest. If fr is incremented, Z will be set if the result is 0; otherwise, Z will be cleared.
AND
Operation: src is ANDed into dest. Z will be set if the result is 0; otherwise, Z will be cleared. W is left holding the

an overflow occurs in the lower nibble; otherwise, DC will be cleared. Z will be set if the result is 0;
otherwise, Z will be cleared. W is left holding the source value in command #2 and #3. If CARRYX is
specified, C is added to result. Insert a CLC before the first Add on a register to avoid strange results.

This instruction is useful for adding the carry into the upper byte of a double-byte sum after the lower
byte has been computed.
