AR0260: 1/6-Inch 1080P High-Definition (HD) Digital Image Sensor

Power-Down Sequence

The output states during hard reset are shown in Table 7.

Soft Reset

The host processor can reset the AR0260 using the two-wire serial interface by writing to

SYSCTL 0x001A. SYSCTL 0x001A[0] is used to reset the AR0260 which is similar to

external RESET_BAR signal.

1. Set SYSCTL 0x001A[0] to 0x1 to initiate internal reset cycle.

2. Reset SYSCTL 0x001A[0] to 0x0 for normal operation.

3. Delay up to 35 ms, depending on EXTCLK frequency.

Soft Reset Operation

Notes:

1. This delay is dependent on EXTCLK frequency.
