BANY as, at, label

Description

(please consult the Xtensa ® Instruction Set Architecture Reference Manual for any cross references and additional information)

BANY branches if any of the bits specified by the mask in address register at are set in address register as. The test is performed by taking the bitwise logical and of as and at and testing if the result is non-zero.

The target instruction address of the branch is given by the address of the BANY instruction, plus the sign-extended 8-bit imm8 field of the instruction plus four. If all of the masked bits are clear, execution continues with the next sequential instruction.

The inverse of BANY is BNONE.

Operation

if (AR[s] and AR[t]) != 032 then
	nextPC ← PC + (imm8724||imm8) + 4
endif
