CALLA

Description
Jump to the address specified by disp24. In parallel with the jump, save the caller’s Upper Context to an available
Context Save Area (CSA). Set register A[11] (return address) to the address of the next instruction beyond the call.
Note:After CALLA, upper context registers are undefined except for A[10] and A[11].
Note:When the PSW is saved, the CDE bit is forced to '1'.
