		const uint8_t	addr,
		const uint8_t	nb )

Send setup parameters to AT42QT1244 peripheral.

Note

No AT42QT1244 peripheral reset done after writing setups, should be customly implemented when needed

Some issues encountered while writing setup block (reason unidentified), resetting the MCU and trying to write again seems to solve issue

[in,out]	hcrc	- Pointer to resulting CRC value
[in]	setup	- Parameters to send
[in]	addr	- Setup address in AT42QT1244 peripheral
