|
|
* - 8 bits wide ports.
|
|
* - Atomic set/reset/toggle functions because special STM8L instruction set.

* - Direct read of input pads regardless of the pad setting.

|

* The STM8L PAL driver supports the following I/O modes:

* @section stm8l_pal_4 Suboptimal behavior
|
|
* The STM8L GPIO is less than optimal in several areas, the limitations
|
|
* should be taken in account while using the PAL driver:
|
|
* - Bus/group writing is not atomic.
|
|
* - Pad/group mode setup is not atomic.
