What is there to explain? The above is rather self-explanatory if you
are in a position to need those features.

I would recommend against learning on an 8535. Its one of the oldest
AVR's and as a result is not supported by JTAG or DebugWire emulation.
Newer better parts (ATmega164P) that do support JTAG or DW are
available for about $1 less than 8535 at DigiKey in quantity 1. At
quantity 25 the cost is essentially the same, whats going on here?.

Beginners should not be subjected to having to learn via burn-and-crash
when one can single step and breakpoint code on the final target for
only $51 for an AVR Dragon.
