4.6.2 Light source current adjustment under 4A

OPR305 series module have the max light source current of 5A. It is much
higher then the GUI presented. GUI programmed for TI DLP3010EVM-LC, the
current on GUI is not the same on our module.
In DLP system, there is a 10bit register storage the brightness message. It can be
adjusted from 0 to 1023. 0 stands for 0A, and 1023 stands for 6A on our module.
When operating OPR305 series module, user should not configure the current more
than 5A(850). In this GUI, when user move the block to the right side, and current
said 2500mA, in fact the number written into register is 700 about 4.2A on OPR305
module. The brightness is much higher than DLP3010EVM-LC, but still not the max
brightness of out module, to reach 5A (850) current, user could set it in advanced
mode.
