STM32G431CBU6 has UART4 !

[mwalt.3]

Hi, 
as advertised
of course , but no : 
- no UART4 as the datasheet , page 14/200 (false because UFQFPN48 has 4 more pins than LQFP48 ?)
- no UART4 as CubeMx : PC10 and PC11 are present , but no UART4
I have got a STM32G431CBU6 from an chinese board maker , nice board with amazing MCU 
tried UART4 as STM32duino's Serial4 : it works , so USART4 is present , officially or not ...
(didn't try the handshaking lines)

as page 14 shows, STM32G431CBU6 should have the uart, only in lqfp48 not.

(lqfp48 has more vdd/vss pins, so pc10/11 missing)

oh right , thanks , I had (don't now why) Rev 2 , but its actually Rev 6
still the issue with CubeMx
