Hi,
I have T56 and just tried to flash MEGA328PB microcontroller, but failed miserably.
I was required to set:
Lock: 3F
High: D9
Low: FF
Ext: 07
But you can't set it with checkboxes.
Is there any option to manually set the hex values?

Thank you!
I thought the whole bitmask is important. So I understand RES bits are disregarded on programming and don't influence anything.
So I must had failed elsewhere :D
