Load Upper Context
Description
Load the contents of the memory block specified by the addressing mode into registers A[10] to A[15] and D[8] to
D[15]. This operation is used normally to restore GPR values that were saved previously by a STUCX instruction.
Note:The effective address (EA) specified by the addressing mode must be aligned on a 16-word boundary. For
this instruction the addressing mode is restricted to absolute (ABS) or base plus short offset (BO).
Note:This instruction may not be used to access peripheral space.
LDUCXoff18 (ABS)(Absolute Addressing Mode)
EA = {off18[17:14], 14b'0, off18[13:0]};
{dummy, dummy, A[10:11], D[8:11], A[12:15], D[12:15]} = M(EA, 16-word);
LDUCXA[b], off10 (BO)(Base + Short Index Addressing Mode)
EA = A[b][31:0] + sign_ext(off10);
{dummy, dummy, A[10:11], D[8:11], A[12:15], D[12:15]} = M(EA, 16-word);
