:) Really? If so, how can you load SRAM via JTAG if TAP in JTAG (as IEEE1149 
standard says) recognizes _only_ 5 commands (used _only_ for testing)? In 
devices with JTAG used for other than testing purposes  (like SRAM/Flash 
loading, debugging etc.) are special commands with codes different than 5 
standard commands (like ISP_xxx in PLDs). There is no way to use JTAG in 
other way than standard 16 states without _special_ codes.

Executing instruction is possible after loading. You say "through" - I 
agree, but my question is: how to say to JTAG "through"?

Sure, all of this is possible _after_ loading. My question is: "how to load 
SRAM"?
Thank you for "learn" suggestion ;-)
