READ_SAME Effects Of Variable Access Size
READ_SAME uses the unadjusted address given in the previous READ_MEM command as a base
address for subsequent READ_SAME commands. When the READ_MEM and READ_SAME size
parameters differ then READ_SAME uses the original base address buts aligns 32-bit and 16-bit accesses,
where those accesses would otherwise cross the aligned 4-byte boundary.
shows some
examples of this.

BDC Serial Interface
The BDC communicates with external devices serially via the BKGD pin. During reset, this pin is a mode
select input which selects between normal and special modes of operation. After reset, this pin becomes
the dedicated serial interface pin for the BDC.
The BDC serial interface uses an internal clock source, selected by the CLKSW bit in the BDCCSR
register. This clock is referred to as the target clock in the following explanation.
