 Zabha extends A and Zacas cite:[zacas] standard extensions by adding _byte_
 (`width=0`) and _halfword_ (`width=1`) support in `width` field for atomic
-memory operation instructions. Byte and halfword AMOs always sign-extend the

+Zabha provides `AMO[ADD|AND|OR|XOR|SWAP|MIN[U]|MAX[U]].[B|H]`. If Zacas is also

 Similar to the AMOs specified in the A extension, the Zabha extension mandates
 that the address contained in the `rs1` register must be naturally aligned to
 the size of the operand. The same exception options as specified in the A
