十进制源和进位被加至目的
十进制源和进位被加至目的
DADD src,dst 或 DADD.W src,dst
DADD.B src,dst
src+dst+C→dst(用十进制)
源操作数和目标操作数被视为带有正号的四个二进制编码十进制 (BCD) 数。源操作数和进位位 (C) 以十进制格式加至目标操作数。源操作数不受影响。目的操作数之前的内容丢失。此结果不针对非 BCD 数定义。
N:如果 MSB 为 1,则置 1;否则复位
Z:如果结果为零,则置 1;否则复位
C:如果结果大于 9999,则置 1
如果结果大于 99,则置 1
V:未定义
OSCOFF,CPUOFF 和 GIE 不受影响。
R5 和 R6 中包含的八位 BCD 数字以十进制格式加至 R3 和 R4 中包含的八位 BCD 数字(R6 和 R4 包含 MSD)。
CLRC ; clear carry
DADD R5,R3 ; add LSDs
DADD R6,R4 ; add MSDs with carry
JC OVERFLOW ; If carry occurs go to error handling routine
RAM 字节 CNT 中的两位十进制计数器递增 1。
CLRC ; clear carry
DADD.B #1,CNT
或
SETC
DADD.B #0,CNT ; equivalent to DADC.B CNT
