I'm studing the AMI Data packing in ADSP-21375 SHARC processor Hardware Reference
becouse i want to transfer on my SRAM(256k x 16bit) only 16bit data
so i could see memory locations of 32bit with 16bit zero.
The only external memory is SRAM.
I initialize :
ustat4 = WS2|HC1|AMIEN|BW16 |PKDIS ;
I set BW16 and PKDIS becouse i read "16-bit data received is zero filled. For transmitted data
only the 16-bit LSB part of the 32-bit data word is written to external memory".
In sram i see that the first 16bit aren't zero but all 32bit data were trasmitted.
I ask if something else must be set.
