1. In Halt/Active-halt mode, this pin behaves as follows:

- The input/output path is disabled.

- If the HSE clock is used for wakeup, the internal weak pull-up is disabled.

- If the HSE clock is off, the internal weak pull-up setting is used. It is configured through Px_CR1[7:0] bits of the

corresponding port control register. Px_CR1[7:0] bits must be set correctly to ensure that the pin is not left floating in

Halt/Active-halt mode.

2. SPI and USTART are not available in STM8AF5286UC, refer to Figure 7: STM8AF52x6 VFQFPN32 32-pin pinout for the

pin names.

4. The PD1 pin is in input pull-up during the reset phase and after reset release.

5. If this pin is configured as interrupt pin, it will trigger the TLI.
