OPERATION
00
ADP digital module is disabled.
01
ADP digital module is enabled.
10
ADP probing mode as an A-device is enabled.
During ADP sensing mode, the VADP_SNS comparator is used. The digital module monitors the comparator
output to ensure that it toggles and the time duration between the rising edge of the comparator output signal is
shorter than T_ADP_SNS. If there is no new rising edge within the T_ADP_SNS period, the module generates
an ADP interrupt.
Figure 19 shows the ADP sensing timing diagram.
Figure 19. ADP Sensing Timing Diagram
During ADP probing, the VADP_PRB comparator is used. The time interval measurement counter is reset, the
comparator is enabled and the VBUS_IADP_SINK current sink is turned on for T_ADP_SINK. The T_ADP_SINK
time is long enough to discharge the VBUS voltage below VADP_DSCHG (guaranteed by design). After that, the
current sink is turned off, the current source VBUS_IADP_SRC is turned on, and the time interval measurement
counter starts to count 32.768-kHz crystal clock cycles. When the VBUS voltage reaches VADP_PRB or the
counter value reaches 255 cycles, the current source is turned off, the time interval measurement counter is
stopped, and the comparator is disabled. If the measured time interval value is lower than T_ADP_LOW[7:0] or
higher than T_ADP_HIGH[7:0], an interrupt is generated. Software sets the limit values so that the operation
fulfills requirements of the OTG 2.0 specification. Figure 20 shows the ADP probing timing diagram.
