對
但建議用SER = dat & 0x80;
比較快
- 192: SER = dat >> 7;
- C:0x03DE E512 MOV A,dat(0x12)
- C:0x03E0 C4 SWAP A
- C:0x03E1 13 RRC A
- C:0x03E2 13 RRC A
- C:0x03E3 13 RRC A
- C:0x03E4 5401 ANL A,#0x01
- C:0x03E6 24FF ADD A,#0xFF
- C:0x03E8 92B7 MOV RD(0xB0.7),C
- 196: SER = dat & 0x80;
- C:0x03FC E512 MOV A,dat(0x12)
- C:0x03FE 33 RLC A
- C:0x03FF 92B7 MOV RD(0xB0.7),C
