TPV – TRIP POINT VALUE

REGISTERS

There are 5 registers that are utilized to set up Trip

Point Values. These registers are used when enabled

by the TRIPctrl register to enter or exit various power

modes. Three of these Trip Point Value registers con-

tain voltage values and two contain current values. The

Trip Point Value registers, their corresponding Com-

pare registers and their enable locations are listed

below:

VPtrip, VCtrip and SHtrip are used as voltage values to

be compared to VPres, VC1res or VC2res and VPres,

respectively, for transition in and out of various power

modes. I+trip and I-trip are used as current values to be

compared to Ires for transition in and out of various

power modes. The format for data in these registers is

left justified. For the purpose of this trip point, only

magnitude is compared, the sign is ignored.
