Functional Description
50.4.1.5.20 WRITE_MEM.sz, WRITE_MEM.sz_WS
Write data at the specified memory address. The reference address is transmitted as three
8-bit packets (msb to lsb) immediately after the command packet. The access attributes
are defined by BAAR[TT,TM]. The hardware forces low-order address bits to zeros for
word and longword accesses to ensure these accesses are on 0-modulo-size alignments. If
the with-status option is specified, the core status byte (XCSR_SB) contained in
XCSR[31–24] is returned after the read data. XCSR_SB reflects the state after the
memory write was performed.
