Depending on the ICP Driver code downloaded in RAM, Flash memory programming can
be fully customized (number of bytes to program, program locations, or selection of the
serial communication interface for downloading).
In Application Programming (IAP)
This mode uses an IAP driver program previously programmed in sector 0 by the user (in
ICP mode).
This mode is fully controlled by user software. This allows it to be adapted to the user
application, (user-defined strategy for entering programming mode, choice of
communications protocol used to fetch the data to be stored etc.)
IAP mode can be used to program any memory areas except sector 0, which is write/erase
protected to allow recovery in case errors occur during the programming operation.
ICC interface
ICP needs a minimum of 4 and up to 6 pins to be connected to the programming tool. These
pins are:

1. If the ICCCLK or ICCDATA pins are only usedas outputs in the application, no signal isolation is necessary.
2. During the ICP session, the programming tool must control the RESET pin. This can lead to conflicts
APPLICATION
POWER SUPPLY
As soon as the programming tool isplugged to the board, even if an ICC session is not in progress, the
ICCCLK and ICCDATA pins arenot available for the application. If they are used as inputs by the
application, isolation such as a serial resistor has to be implemented in case another device forces the
signal. Refer to the programmingtool documentation for recommended resistor values.
between the programming tool and the application reset circuit if it drives more than 5 mA at high level
(push pull output or pull-up resistor < 1K). A schottky diode can be used to isolate the application RESET
circuit in this case. When using a classical RC network with R>1K or a reset management IC with open
drain output and pull-up resistor >1 K, no additional components are needed. In all cases the user must
