8.27.2.3 Addressing Modes

as understands the following addressing modes for the SH. R n in the following refers to any of the numbered registers, but not the control registers.

R n

Register direct

@R n

Register indirect

@-R n

Register indirect with pre-decrement

@R n +

Register indirect with post-increment

@( disp , R n )

Register indirect with displacement

@(R0, R n )

Register indexed

@( disp , GBR)

GBR offset

@(R0, GBR)

GBR indexed

addr

@( disp , PC)

PC relative address (for branch or for addressing memory). The as implementation allows you to use the simpler form addr anywhere a PC relative address is called for; the alternate form is supported for compatibility with other assemblers.

# imm
