#169496 - No problem
Responding to: ???'s previous message
Hi Jan!

I am actually working with that chip, programming with Flip. I only had one problem: the chips (PLCC44 from Digikey) have the FCB (Fuse Configuration Byte) bits 2 to 0 with 011, wich means that after reset, the bootloader will be executed!

Simply, when load the program with Flip, set FCB to the desire value: bit7 X2 mode (0: 6 clocker), and bits 2 to 0: 111 (reset at 0x0000) or what ever you need (table 20 page 34 specs).

Daniel
