9.2.2 Power-Down (PD) Mode

The device also features a deep power-down mode (PD) to reduce the power consumption at very low

throughput rates.

The following steps must be taken to enter PD mode:

1. Write 69h to register address 05h to unlock the RST_PWRCTL_REG register.

2. Set the PWRDN bit in the RST_PWRCTL_REG register to 1b. The device enters PD mode on the rising edge

of the CONVST/CS signal.

In PD mode, all analog blocks within the device are powered down; however, the interface remains active and

the register contents are also retained. The RVS pin is high, indicating that the device is ready to receive the

next command.

In order to exit PD mode:

1. Clear the PWRDN bit in the RST_PWRCTL_REG register to 0b.

2. The RVS pin goes high, indicating that the device has started coming out of PD mode. However, the host

controller must wait for the tPWRUP time (see the Timing Requirements: Asynchronous Reset table) to elapse

before initiating a new conversion.
