s = 0: Rs-code encodes G0..G15 for Rs
s = 1: Rs-code encodes L0..L15 for Rs
Ld-code encodes L0..L15 for Ld
Notation:
LDW.P Ld, Rs
Description:
The Load instruction of post-increment address mode transfers data from the addressed
memory location, Ld is used as an address, into a register Rs.
The content of the destination register Ld is used as an address into memory address space,
then Ld is incremented according to the specified data size of a word by 4, regardless of
any exception occurring.
