ST.DA
Store Double-word from Address Registers
Description
Store the value in the address register pair A[a]/A[a+1] to the memory location specified by the addressing mode.
The value in the even register A[a] is stored in the least-significant memory word, and the value in the odd register
(A[a+1]) is stored in the most-significant memory word.
