below 2mA at 5V. If PA3 is used as output push-pull, then the application must be switched

off to allow the tool to take control of the RESET pin (PA3). To allow the programming tool to

drive the RESET pin below VIL, special care must also be taken when a pull-up is placed on

PA3 for application reasons.

Caution:

During normal operation the ICCCLK pin must be internally or externally pulled- up (external

pull-up of 10 k

Ω mandatory in noisy environment) to avoid entering ICC mode unexpectedly

during a reset. In the application, even if the pin is configured as output, any reset will put it

back in input pull-up.
