Hello,

Please see "Figure 13 Generation of the Effective Address of a Context Save Area (CSA)" under the section "4.1.1 Context Save Area " in the TC3xx_Architecture_vol1  for details.

In simple, from actual PCXI register you can decode the address of previous context (PCXS + 6 bit shifted PCXO followed by 0 bits).

Regards,

Prudhvi.
