BNE as, at, label
(please consult the Xtensa ® Instruction Set Architecture Reference Manual for any cross references and additional information)
BNE branches if address registers as and at are not equal.
The target instruction address of the branch is given by the address of the BNE instruction, plus the sign-extended 8-bit imm8 field of the instruction plus four. If the registers are equal, execution continues with the next sequential instruction.
The inverse of BNE is BEQ.
