Soft Reset

The host processor can reset the AS0260 using the two-wire serial interface by writing to

SYSCTL 0x001A. SYSCTL 0x001A[0] is used to reset the AS0260 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.

2. Assumes that CONFIG/GPIO1 = 1.

Shutdown Mode

The shutdown mode is entered when the SHUTDOWN pin is asserted. All power to the

AS0260 is disabled and no state, register, or patch information is retained. De-assertion

of the SHUTDOWN pin will cause a full POR.
