18 / 123 page  Flash programmable memory ST7FOXU0 18/123 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. Figure 4.
