    function: Absolute Call Within 2K Block
    syntax: ACALL code address
    source_title: "8051 Instruction Set: ACALL"
    description: "ACALL unconditionally calls a subroutine at the indicated code address . ACALL pushes the address of the instruction that follows ACALL onto the stack, least-significant-byte first, most-significant-byte second. The Program Counter is then updated so that program execution continues at the indicated address. The new value for the Program Counter is calculated by replacing the least-significant-byte of the Program Counter with the second byte of the ACALL instruction, and replacing bits 0-2 of the most-significant-byte of the Program Counter with 3 bits that indicate the page. Bits 3-7 of the most-significant-byte of the Program Counter remain unchaged. Since only 11 bits of the Program Counter are affected by ACALL, calls may only be made to routines located within the same 2k block as the first byte that follows ACALL."

    description: "Green rows below show the edited const16-address forms that replace legacy 8-bit immediate data. Description: ADD and ADDC both add the value operand to the value of the Accumulator, leaving the resulting value in the Accumulator. The value operand is not affected. ADD and ADDC function identically except that ADDC adds the value of operand as well as the value of the Carry flag whereas ADD does not add the Carry flag to the result. The Carry bit (C) is set if there is a carry-out of bit 7. In other words, if the unsigned summed value of the Accumulator, operand and (in the case of ADDC) the Carry flag exceeds 255 Carry is set. Otherwise, the Carry bit is cleared. The Auxillary Carry (AC) bit is set if there is a carry-out of bit 3. In other words, if the unsigned summed value of the low nibble of the Accumulator, operand and (in the case of ADDC) the Carry flag exceeds 15 the Auxillary Carry flag is set. Otherwise, the Auxillary Carry flag is cleared. The Overflow (OV) bit is set if there is a carry-out of bit 6 or out of bit 7, but not both. In other words, if the addition of the Accumulator, operand and (in the case of ADDC) the Carry flag treated as signed values results in a value that is out of the range of a signed byte (-128 through +127) the Overflow flag is set. Otherwise, the Overflow flag is cleared."

    description: "MOVC is the dedicated 8051e instruction class for deterministic reads from CONST read-only memory. MOVC transfers immutable data from the CONST domain into writable destinations such as: - Accumulator (A) - general registers (R0-R7) - Internal RAM - DPTR The legacy addressing forms - MOVC A,@A+PC - MOVC A,@A+DPTR are removed and no longer supported. These legacy forms depended on implicit address generation and mixed executable code with read-only data access. In 8051e, MOVC is restricted to the dedicated CONST memory domain and uses only explicit deterministic addressing. Supported 8051e MOVC access classes are: - direct CONST access through const addr16 - dynamic CONST read through DPTR-based explicit access, where defined by TDM TDM-constrained dynamic read: For MOVC A,DPTR , the data width and interpretation are constrained by TDM. Allowed result forms are: - 2*8-bit - 1*16-bit For MOVC DPTR,const addr16 , the loaded pointer representation must satisfy: - 3*8-bit - 2*8-bit - 1*16-bit MOVC preserves strict separation between: - CODE - CONST - DATA and provides an analyzable, deterministic path for all read-only constant access."
