bit 3-0

CS_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, CS_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.

CS_S1_RATIO[2:0]: Determines the voltage divider ratio as shown below when the stimulus response

is set to connect a voltage divider (that is, CS_S1_R1[3:0] = 0110b, 1001b, or 1100b).

000 =0.25

001 =0.33

010 =0.4

011 =0.5

100 =0.54

101 =0.6

110 =0.66

111 = Do not use.
