bit 3-0

CS_S2_R2<3:0>: Defines the stimulus response as shown below:

0000

Remove previous response on DPOUT and DMOUT

0001

Apply voltage on DPOUT (Note 1).

0010

Apply voltage on DMOUT (Note 2).

0011

Apply voltage on DPOUT and DMOUT.

0100

Connect resistor from DPOUT to GND (Note 1).

0101

Do not use.

0110

Connect voltage divider from VBUS to GND with “center” at DPOUT (Note 1).

0111

Connect resistor form DMOUT to GND (Note 2).

1000

Do not use.

1001

Connect voltage divider from VBUS to GND with “center” at DMOUT (Note 2).

1010

Connect

 200resistor from D

POUT to DMOUT.

1011

Do not use.

1100

Connect voltage divider from VBUS to GND with ‘center’ at DPOUT and DMOUT.

1101

Connect resistor from DPOUT to GND and DMOUT to GND.

1110

If CS_STIM2 = 000, the 15 k

pull down resistors applied to D

POUT and DMOUT during emu-

lation reset are not removed. If CS_STIM2 = 111, the 15 k

pull down resistors applied to

DPOUT and DMOUT during emulation reset are removed. For all other CS_STIM2 settings,

whatever was applied is not changed.

1111

= Same as 1110 case above.

Note 1:

If CS_STIM2<2:0> = 000b and no other response was applied to the DPOUT pin, the 15 k pull-down

resistor applied to the DPOUT pin during emulation reset is not removed. Otherwise, the previous response

is left on the DPOUT pin (if applicable) or the 15 k pull-down resistor is removed.

If CS_STIM2<2:0> = 000b and no other response was applied to the DMOUT pin, the 15 k pull-down

resistor applied to the DMOUT pin during emulation reset is not removed. Otherwise, the previous response

is left on the DMOUT pin (if applicable) or the 15 k pull-down resistor is removed.

bit 5-4

CS_S2_PUPD<1:0>: Determines the magnitude of the pull-down current applied on the DPOUT and

DMOUT pins when the stimulus response is to apply a voltage and the voltage magnitude is set at pull-

down (0000b). The bit decode is as follows:

=10 µA

=50 µA

=100 µA

=150 µA
