HVSP: Reviving on old ATtiny13

HVSP needed! When ISP fuse is disabled and DW not working.

High Voltage Serial Programming – (sometimes known as SHVP).

The AVR Studio 4 way:

Connect. Select HVSP. Go.

THE AtmelStudio 7 way:

View > Available Atmel Tools shows only the JTAGICE mkII and the Simulator. Go to Tools > Add target. Or write STK in the upper-right box called “Quick Launch” and the Add target dialog appears. (I tried also PICkit, but it’s still not there)
