Jump if bit is not set. Exchange the data between acc and Rx. OR carry with given bit b, stores result in carry. AND each bit of acc with same bit of content of Rx, stores result in acc.
8051/8951 microcontroller Instruction Set
Cjne a, num, label. Jump if accumulator is not zero.
Rotate acc one bit left. No of bytes occupied. Swap nibbles within the accumulator. Rotate accumulator left through carry flag. Jump to the label if content of accumulator is 0.
OR each bit of acc with same bit of immediate num, stores result in acc. Add the immediate num with acc and carry, stores result in acc. Instruction of the is listed below. OR each bit of direct add with same bit of immediate num, stores result in add.
Logical OR for byte variable.
Add 1 to acc. Copy the data in acc to address in Rp. Choosing Battery for Robots. Multiply acc and register B. Jump to the address created by adding the contents on accumulator and dptr. The address is formed by adding acc and PC and its content is copied to acc. XOR each bit of acc with same bit of immediate num, stores result in acc. Jump if carry is not set.
Decimal adjust accumulator for addition. OR each bit of acc with same bit of content in add, stores result in acc. Cjne Rp, num, label. Subtract immediate num and carry from acc; stores the result in acc.
8051 Instruction Set
XOR each bit of direct add with same bit of immediate num, stores result in add. Pushes the content of Acc on stack and load it will absolute srt range address sadd. Compare and jump if not equal. Compare the content of accumulator with immediate number and if not equal jump to label.

Here one can find complete instruction set of microcontroller. Rotate accumulator right through carry flag. Copy the data from acc to Rx. Copy the immediate byte num to the address in Rp. Jump if bit is set. Copy the content of acc to the external add in DPTR.
Jump to the label if content of accumulator is not 0. Copy the immediate data num in to Rx. Copy the data from Rx to acc.
