Assembler Syntax:
LRA Rn,D
LRA label,D
Description:
The PC is added to the specified displacement and the result is stored in destination D. The PC contains
the address of the next instruction. The displacement is a 2’s complement 32-bit integer that represents
the relative distance from the current PC to the destination PC. Long Displacement and Address Register
PC Relative addressing modes may be used. See Section A.10 for restrictions. Note that if D is SSH,
the SP will be preincremented by one.
CAUTION
See restrictions in Section A.10.6 concerning Rn, Mn, and Nn registers as a
destination.
