+Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program it (through TPI) fails. Instead, the memory retains the old contents.
+<code>
+ Solution: Mind the limited programming supply voltage range of these devices.
+ In-circuit programming through TPI is only guaranteed by the datasheet at Vcc = 5 V.</code>
+STK 600 also supports TPI
