JB bitoffset jump if bit set. This specifies dataeheet address of the next instruction to execute. The ‘s predecessor, thewas used in the keyboard of the first IBM PCwhere it converted keypresses into the serial data stream which is sent to the main unit of the computer. RLC A rotate left through carry. Gives the parity XOR of the bits of the accumulator, A.

Most systems respect this distinction, and so are unable to download and directly execute new programs. JNZ offset jump if non-zero. MOV bitC. Carry bitC.

Intdl bitoffset jump if bit set with clear. JZ offset jump if zero.

The SJMP short jump opcode takes the signed relative offset byte operand adtasheet transfers control there relative to the address of the following instruction. Overflow flagOV.

Bits are always specified by absolute addresses; there is no register-indirect or indexed addressing. Register select 1, RS1. One feature of the core is the inclusion of a boolean processing engine which allows bit -level boolean logic operations to be carried out directly and efficiently on select internal registersports and select RAM locations.

XRL Adata.

SUBB Adata. RL A rotate left.

ANL addressA. RR A rotate right. For the latter, there are explicit instructions to jump on whether or not the accumulator is zero. Most clones also have a full bytes of IRAM. Set when addition produces a carry from bit 3 to bit 4.

The following is a partial list of the ‘s registers, which are memory-mapped into the special function register space:. Retrieved 6 January Often datasheer as the general register for bit computations, or the “Boolean accumulator”.

ORL addressdata. ADDC Adata. Retrieved 11 October By using this site, you agree datazheet the Terms of Use and Privacy Policy. JC offset jump if carry set. Retrieved 22 August ORL addressA. Set when addition produces a signed overflow. Today, s are still available as discrete parts, but they are mostly used as silicon intellectual property cores.

IRAM from 0x00 to 0x7F can be accessed directly.

Intel MCS-51

Set when banks at 0x10 or 0x18 are in use. The only register on an that is not memory-mapped is the bit program counter PC.

This part was available in a ceramic package with a clear quartz window over the top of the die so UV light could be used datashete erase the EPROM memory. ADD Adata. The last digit can indicate memory size, e.
