OR carry with complement of given bit b, stores result in carry. XOR each bit of acc with same bit of direct add num, stores result in add.
What is Web Browser. AND carry with complement of given bit b, eet result in carry. Cjne a, add, label. Copy the data in add to address in Rp.
NPTEL :: Electronics & Communication Engineering – Microcontrollers and Applications
Exchange the data between acc and Rx. Subtract 1 from acc.
Compare the content of Rx with the immediate number and if not equal jump to label. Logical AND for bit variables. Jump if accumulator is zero. OR each bit of acc with same bit of direct add num, stores result in add. Copy the content of acc to the external add in Rp.
Exchange accumulator with bit variable. Add the immediate num with acc and carry, stores result in acc. Rotate acc one bit right. Compare the content of location in Rp with immediate number and if not equal jump to label.
Copy the data that is at address in Rp to add. Copy the content of acc to the external add in DPTR. Copy the data from Rx to direct address add. Interface SD Card with Arduino. Rotate accumulator right through carry flag.
Take a jump to absolute long range address sadd. Subtract the content of add insruction carry from acc; stores the result in acc. Copy the immediate data num in to direct address. Copy the data from Rx to acc.
Subtract 1 from Rr. Copy the data from direct address add to acc. Add the immediate num with acc and stores result in acc. Add the data in Rx with acc and carry, stores result in acc.
8051 Instruction Set
Exchange upper and lower nibble of acc. Jump to label if given bit is cleared to 0. Copy carry to bit b. Jump to label if carry is set to 1. AND each bit of acc with same bit of content of add given by Rp, stores result in acc. Add the data at the address in Rp with inztruction and carry, stores result in acc.
Jump if carry is set. Add 1 to DPTR. Jump to label if given bit is set to 1.
XOR each bit of direct add with same bit of immediate num, stores result in add. Here one can find complete instruction set of microcontroller. Copy the content of external add in Rp to acc. Copy the immediate data num in to acc.
