LCD controller (STM8L152xx only)
In the following table, data is guaranteed by design. Not tested in production.
VLCD external capacitor (STM8L152xx only)
The application can achieve a stabilized LCD reference voltage by connecting an external
capacitor CEXT to the VLCD pin. CEXT is specified in Table 45.
