Full Chip Erase
The ISP command "Full Chip Erase" erases all user Flash memory (fills with FFh) and
sets some bytes used by the bootloader at their default values:
•
BSB = FFh
•
SBV = FCh
•
SSB = FFh
The Full Chip Erase does not affect the bootloader.
Checksum Error
When a checksum error is detected, send ‘X’ followed with CR&LF.
Flow Description
Overview
An initialization step must be performed after each Reset. After microcontroller reset,
the bootloader waits for an autobaud sequence (see section ‘Autobaud Performances’).
When the communication is initialized, the protocol depends on the record type
requested by the host.
FLIP, a software utility to implement ISP programming with a PC, is available from the
Atmel web site.
Communication Initialization
The host initializes the communication by sending a ’U’ character to help the bootloader
to compute the baudrate (autobaud).
