		int	`biasLevel`
	)

Configure the bias level for a specific segment line.

Note: When DSC is active, each configuration takes up 4 bits in the corresponding Segment Registers (SEGD4L/SEGD4H for Series 0 and 1, AREGA/AREGB for Series 2) which defines bias level. For optimal use of this feature, the entire register set should be set at once in a optimized routine. Therefore, this function shows how to correctly configure the bias levels and should be used with care.

Parameters

[in]	`comLine`	A COM line number, between 0 and 7 for Series 0 and 1. For Series 2, max is LCD_COM_NUM, defined in device-specific headers.
