Note:

The slope control of all GPIO pins, except true open drain pins, can be programmed. By

default, the slope control is limited to 2 MHz.

1. At power-up, the PA1/NRST pin is a reset input pin with pull-up. To be used as a general purpose pin (PA1), it can be

configured only as output open-drain or push-pull, not as a general purpose input. Refer to Section Configuring NRST/PA1

pin as general purpose output in the STM8L15x and STM8L16x reference manual (RM0031).

2. Available on STM8L152xx devices only.

3. In the 3.6 V tolerant I/Os, protection diode to VDD is not implemented.

[ ] Alternate function remapping option (if the same alternate function is shown twice, it indicates an exclusive choice not a

duplication of the function).

5. In the 5 V tolerant I/Os, protection diode to VDD is not implemented.

6. A pull-up is applied to PB0 and PB4 during the reset phase. These two pins are input floating after reset release.

7. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up and protection diode to VDD are

not implemented).

8. Available on STM8L151xx devices only.

9. The PA0 pin is in input pull-up during the reset phase and after reset release.

10. High Sink LED driver capability available on PA0.
