Pinouts and pin description

1. Refer to
2. Reset state is shown in bold.
3. In Halt/Active-halt mode this pad behaves in the following way:
4. On this pin, a pull-up resistor as specified in
5. AIN12 is not selectable in ADC scan mode or with analog watchdog.
6. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, week pull-up, and protection diode to V
7. The PD1 pin is in input pull-up during the reset phase and after reset release.
8. If this pin is configured as interrupt pin, it will trigger the TLI.

- 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, internal weak pull up setting from corresponding OR bit is used
By managing the OR bit correctly, it must be ensured that the pad is not left floating during Halt/Active-halt.

Alternate function remapping
As shown in the rightmost column of
different I/O ports by programming one of eight AFR (alternate function remap) option bits.
Refer to
default alternate function is no longer available.
To use an alternate function, the corresponding peripheral must be enabled in the peripheral
registers.
Alternate function remapping does not effect GPIO capabilities of the I/O ports (see the
GPIO section of the STM8S and STM8A microcontroller families reference manual,
RM0016).
