In MOVEA.L, the destination of the move is an address register.

Move.L moves a 32-bit value to a register or to memory, sets the N and Z
condition codes to reflect the data moved and clears the V and C condition
codes.

Move.A moves a 16- or 32-bit value to an address register; the condition
codes are not affected. A 16-bit source is sign-extended to 32 bits in
the destination register.

What's the difference between 68000 assembler instructions
