Function Description
Auto Scale Control of Solar_UV/UV mode
ASC mode is active; UV_IT and UV-G are automatically scaled by internal circuit. The
7
UV_ASC#
0 UV_IT and UV_G can only be read as the internal scaled ones, and UV Data would be
defined as 16 bits of [15:0].
1 UV_IT and UV-Gain are controlled by register 0x10[6:4] and 0x10[3:2].
