Charge Rationing Threshold Registers

The Charge Rationing Threshold registers set the

maximum allowed charge that will be delivered to a

portable device. Every time the Total Accumulated

Charge registers are updated, the value is checked

against this limit. If the value meets or exceeds this

limit, the RATION(1/2) bit is set and action taken

according

the

RATION_BEH1<1:0>

and

RATION_BEH2<1:0> bits.
