ADC sleep time before starting another cycle
x0 = Continuous Loop
x1 = 4.5 ms
x2 = 9.0 ms
x3 = 13.5 ms
Coulomb Counter Enable
x0 = Disable
x1 = Enable
Coulomb Counter Reset Enable
x0 = Do not reset CC
x1 = CC reset
Enable Touch Screen Pen Detect Bias
x0 = Disabled
x1 = Enabled
ADC Round Robin Start Signal
x0 = Stop round robin after the current cycle
x1 = Start round robin
Bring the ADC out of low power state, this overrides wake from sleep
x0 = Disable in low power
x1 = Enable at full power
