For use with ATMega 48 (old Arduino?), 328 (UNO, Pro Mini) and 2560 (Mega2560) chips, what is the capability for the AVRISP and USBASP programmers on:
Can it read, write fuse?
Can it read, write Program Flash?
Can it work 3.3 and 5 volts?
What workable clock frequency range on the MCU?
Can it be used under Arduino ISP to write to board so as to erase the bootloader and use the FULL flash space for big user program (eliminate boot loader saves 0.5 to 8KB space on above Arduino boards)?
Can it be used with ATMel factory software development tools (Atmel studio and associated tools) to use MCU on chip hardware based breakpoint (Debug wire, JTag, or other names, as on different MCU)?
Many thanks in advance
