Retrieved 11 October Gives the parity XOR of the bits of the accumulator, A. Views Read Edit View history. The only register on an that is not memory-mapped is the bit program counter PC. The last digit can indicate memory size, e. Today, s are still available as discrete parts, but they are mostly used as silicon intellectual property cores.

Set when banks at 0x10 or 0x18 are in use. It is an example of a complex instruction set computerand has separate memory spaces for program instructions and data Harvard architecture. Set when addition produces a carry from bit 3 to bit 4.

As of [update]new derivatives are still developed by many major chipmakers, and major compiler suppliers such as IAR SystemsKeil and Altium Tasking continuously release updates.

Intel MCS-51

Overflow flagOV. XRL addressA.

MOV bitC. MOV Adata. Since data could be in one of inetl memory spaces, a mechanism is usually provided to allow determining to which memory a pointer refers, either by constraining the pointer type to include the memory space, or by storing metadata with the pointer.

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 to erase the EPROM memory. XRL addressdata.

Instruction mnemonics use destinationsource operand order. Set when banks at 0x08 or 0x18 are in use.

ORL Cbit. May be read and written by software; not otherwise affected by hardware. Instructions that operate on single bits are:.

You can help by adding to it.

CJNE Adata,offset. XRL Adata.

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. Several C compilers are available for themost of which allow the programmer to specify where each variable should be stored in its six types of memory, and provide access to specific hardware features such as the multiple register banks and bit manipulation instructions.

SUBB Adata.

Often used as the general register for bit computations, or the “Boolean accumulator”. The ‘s predecessor, thewas used in the keyboard of the first IBM Nitelwhere it converted keypresses into the serial data stream which is sent to the main unit of the computer.

Bits are always specified by absolute addresses; there is no register-indirect or indexed addressing.

Enhancements mostly include new peripheral features and expanded arithmetic instructions. Single-board microcontroller Special function register. JNZ offset jump if non-zero. External data memory XRAM is a third address space, also starting at datasheeg 0, and allowing 16 bits of address space.

This made them more suitable for battery-powered devices. ANL addressA.
