My embeded system  with MIPS CPU uses 4 modules of SDRAM module with  16 bits 
of 
data bus.
(Each module has 64MB, that is the configuration is  32Mx16=512Mb, that is the 
whole SDRAM is 
256MB)

  I want to write some data to SDRAM via JTAG.
Is my thinking correct saying that 
mwh 0x123456 0xac23
will write the data 0xac23 ( 4!! bytes) on the 0x123456 address?

and command
mdh 0x123456
will display the 16bits = 4 !! bytes of data that is on the address 123456

Thanks
