Specify AVR device. -b Override RS-232 baud rate. -B Specify JTAG/STK500v2 bit clock period (us). -C Specify location of configuration file. -c Specify programmer type. -D Disable auto erase for flash memory -i ISP Clock Delay [in microseconds] -P Specify connection port. -F Override invalid signature check. -e Perform a chip erase. -O Perform RC oscillator calibration (see AVR053). -U :r|w|v:[:format] Memory operation specification. Multiple -U options are allowed, each request is performed in the order specified. -n Do not write anything to the device. -V Do not verify. -u Disable safemode, default when running from a script. -s Silent safemode operation, will not ask you if fuses should be changed back. -t Enter terminal mode. -E [,] List programmer exit specifications. -x Pass to programmer. -y Count # erase cycles in EEPROM. -Y Initialize erase cycle # in EEPROM. -v Verbose output. -v -v for more. -q Quell progress output. -q -q for less. -l logfile Use logfile rather than stderr for diagnostics. -?
