* RLC[.W] | 通过进位左旋 | ||
* RLC.B | 通过进位左旋 | ||
语法 | RLC dst 或 RLC.W dst | ||
RLC.B dst | |||
操作 | C←MSB←MSB-1 ....LSB+1←LSB←C | ||
仿真 | ADDC dst,dst | ||
说明 | 如图 4-38中所示,目的操作数向左移动一个位置。进位位 (C) 被移入 LSB,而 MSB 被移入进位位 (C)。 | ||
状态位 | N: | 如果结果为负则置 1,如果为正则复位 | |
Z: | 如果结果为零则置 1,否则复位 | ||
C: | 从 MSB 载入 | ||
V: | 如果一个算术溢出发生:初始值为 04000h≤dst<0C000h,则置 1;否则复位 | ||
如果一个算术溢出发生:初始值为 040h≤dst<0C0h,则置 1;否则复位 | |||
模式位 | OSCOFF,CPUOFF 和 GIE 不受影响。 | ||
示例 | R5 被左移一个位置。 |
RLC R5 ; (R5 x 2) + C -> R5
示例 | 输入 P1IN.1 信息被移入 R5 的 LSB。 |
BIT.B #2,&P1IN ; Information -> Carry
RLC R5 ; Carry=P0in.1 -> LSB of R5
示例 | MEM(LEO) 内容被左移一个位置。 |
RLC.B LEO ; Mem(LEO) x 2 + C -> Mem(LEO)
RLA 的替代指令
汇编程序并不识别指令:
RLC @R5+ RLC.B @R5+ RLC(.B) @R5
它们必须由以下指令替代:
ADDC @R5+,-2(R5) ADDC.B @R5+,-1(R5) ADDC(.B) @R5
