Read as ‘0’
bit 6
S1_TD_TYPE:
Stimulus 1 Timer Behavior Determination bit
1
= The stimulus timer controls how long the response is applied after the stimulus is detected; the response
is applied immediately and held for the duration of the timer then removed (if the stimulus has been
removed)
0
= The stimulus timer is a delay from when the stimulus is detected until the response is performed

STIM1<2:0>:
Stimulus 1 Determination Usage bits
Determines the Stimulus 1 that is used as shown below. Note that the lower threshold for the window
comparator option is fixed at 400 mV and only applies to the DPOUT pin. This setting cannot be used for
the DMOUT port.
000
= (default) VBUS voltage is ready to be applied before port power switch is closed; next stimulus
will not wait for this to be removed
001
= DPOUT voltage is higher than the threshold (S1_TH)
010
= Window comparator; DPOUT voltage is lower than the threshold (S1_TH) and DPOUT voltage
higher than the fixed threshold
011
=DMOUT voltage is higher than the threshold (S1_TH)
100
= Do not use
101
= Do not use
110
=DPOUT voltage is higher than the threshold (S1_TH)
111
=VBUS voltage is present after port power switch is closed; next stimulus will not wait for this to be
removed.
