Interrupt Source register (address R = 08h) bit description
Description
This bit has two functions:
When the Carkit Interrupt Delay register is 0h and the voltage on the
CR_INT pin is below the carkit interrupt threshold (0.4 V to 0.6 V), this bit
is set.
0 — Voltage on the CR_INT pin is above the carkit interrupt threshold
(0.4 V to 0.6 V).
1 — Voltage on the CR_INT pin is below the carkit interrupt threshold
(0.4 V to 0.6 V).
When the Carkit Interrupt Delay register is nonzero and the voltage on the
CR_INT pin is below the carkit interrupt threshold (0.4 V to 0.6 V) for a
period of time defined in the Carkit Interrupt Delay register, this bit is set.
0 — No event
1 — The carkit stereo interrupt event is detected.
In power-down mode, this bit is fixed as logic 0.
Set when bit BDIS_ACON_EN is set, and the ISP1302 enables the DP
pull-up resistor after detecting the B-device disconnect (SE0).
0 — No event
1 — BDIS_ACON is detected.
Indicates the status of pin ID.
0 — ID pin is not floating.
1 — ID pin is floating.
DM single-ended receiver output.
0 — LOW
1 — HIGH
Indicates the status of pin ID:
0 — ID pin is not grounded.
1 — ID pin is grounded.
In power-down mode, this bit is fixed as logic 0.

This bit has two functions:
For the A-device (bit ID_GND = 1), it acts as the V
0 — V
1 — V
For the B-device (bit ID_GND = 0), it acts as B_SESS_END (B-device
session end detector).
0 — V
1 — V
In power-down mode, this bit is fixed as logic 0.
