Description
The halfword data in the specified memory location is transferred to the rd register after being sign-
extended to 32 bits. The rb register contains the memory address to be accessed. Following data
transfer, the address in the rb register is incremented by 2.
Caution
(1) The rb register must specify a halfword boundary address (least significant bit = 0). Specifying
an odd address causes an address misaligned exception.
(2) If the same register is specified for rd and rb, the incremented address after transferring data is
loaded to the rd register.
