Hi all!

I just checked the HW behavior regarding this bit-shift stuff.

When you write an id (id28:0) to the registers

A1R: (id15:0)

A2R: (id28:16)

you get the following on the physical bus:

(SOF)(id28:18)(SRR)(IDE)(id17:0)(RTR).....

So, if this is what the application requires, the bit-shifting macros from the library are not required.
