示例1: SFR_W

/*From several sources, since none said the same thing:
 The decimal adjust instruction is associated with the use of the ADD and ADDC instructions.
 The eight-bit value in the accumulator is adjusted to form two BCD digits of four bits each.
 If the accumulator contents bits 0-3 are greater than 9, OR the AC flag is set, then six is added to
 produce a proper BCD digit.
 If the carry is set, OR the four high bits 4-7 exceed nine, six is added to the value of these bits.
 The carry flag will be set if the result is > 0x99, but not cleared otherwise */
