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 is not available in STM8AF5286UC, refer to Figure 7: STM8AF5286UC VFQFPN32 32-pin pinout for the pin names.
3. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, week pull-up and protection diode to V_DD are
not implemented)
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.
