:)Looks like there is a command to query if the programmer has address auto
increment:
:)
:);**** Return autoincrement address support
:)w51:
:) cpi u_data,'a' ; 'a' Return address auto increment
:) brne w5
:) ldi u_data,'Y' ; putc('Y'); // supports autoinc
:) rcall putc
:) rjmp waitcmd
Try the latest cvs now. I just committed the changes to implement handing of
the the auto incr addr feature.
Dumping the entire 8K of flash from an 8515 took 46 second without auto incr
and 21 second with. YMMV.
