Table 6. Parameters
Parameter Name Field Usage Field Format
commandsize Defines how many bytes of additional parameters the command contains. In this case it’s value
should be 4 (for the eepromsize, signalpagel and signalbs2 parameters). The STK500 may
accept more parameters in later revisions.
1 byte
eeprompagesize EEPROM page size in bytes. 1 byte
signalpagel Defines to which port pin the PAGEL signal should be mapped. Example: signalpagel = 0xD7. In
this case PAGEL should be mapped to PORTD7.
1 byte
signalbs2 Defines to which port pin the BS2 signal should be mapped. See signalpagel. 1 byte
ResetDisable Defines whether a part has RSTDSBL Fuse (value = 1) or not (value = 0). 1 byte
