bit 3-0

S1_TH[3:0]: Defines the threshold value as shown below for the specified stimulus. If the stimulus is

VBUS voltage is ready to be applied or applied (that is, STIM1[2:0] = 000b or 111b), the threshold

value is ignored.

0000 = 400 mV

0001 = 400 mV

0010 = 400 mV

0011 = 300 mV

0100 = 400 mV

0101 = 500 mV

0110 = 600 mV

0111 = 700 mV

1000 = 800 mV

1001 = 900 mV

1010 = 1400 mV

1011 = 1600 mV

1100 = 1800 mV

1101 = 2000 mV

1110 = 2200 mV

1111 = Do not use.

Note 1: The Legacy charger emulation profiles do not use these settings. Whenever a Legacy charger emulation

profile is applied within the DCE Cycle, these controls are not updated and must be ignored. These

settings are only used by the BC1.2 CDP and DCP charger emulation profiles.
