- P: Programmable
- (P): Programmable but modification to xml file for the device is required (cf. AVR-STK500 and Atmel Studio 6)
- [1]: Programmable by using ISP port. Although RESET is active HIGH, which is the invert of AVRs, STK500 (clone) automatically takes care of it.
- [2]: Reading the first byte of the signature is unstable. Note: PP of Atmel AVR Dragon works fine for this part.
- [3]: The fuse setting of setup time 0ms causes issue in entering PP mode.
- [4]: Need to fix Atmel's buggy configuration file (Studio 7: 7.0\packs\atmel\ATtiny_DFP\1.0.68\atdf\ATtiny1634.atdf; Studio 6: devices\ATtiny1634.xml; Studio 4: Partdescriptionfiles\ATtiny1634.xml) at the property PpControlStack. (cf. http://avrdude-dev.nongnu.narkive.com/hxkmK5bx/what-s-missing-for-a-new-release-attiny1634)
- [5]: Chip Rev B has a fatal hardware flaw and does not work w/ PP (cf. Atmel's official ATtiny2313/V datasheet, Errata ATtiny2313 Rev B). Current Rev C is no problem.
- [6]: Possible microcontroller flaw. Unprogramming RSTDISBL and/or SPIEN fuse bit(s) can be done after several tries (cf. AVRSV-2558: HVPP for ATtiny2313A does not work on STK500 (in Atmel's official Atmel Studio 7 Release Note, 5. Features and Bugs or Atmel Studio 6.2 Release Note, 5.3 Known Issues)). Note: PP of Atmel AVR Dragon works fine for this part if and only if RSTDISBL is not programmed, and Dragon can never unprogram RSTDISBL.
