RESET OPERATION

The ADS8201 can be reset in two ways: hardware reset and software reset. A hardware reset can be asserted

via the RST pin. A software reset can be asserted through the serial interface by writing AAh to the Reset SCR

(address 09h). While hardware reset can be asserted at any time, software reset cannot be initiated if the device

is in power-down mode. As long as the device is in any other of the ADC operating modes, a software reset can

be issued. Once the reset is issued, the device comes back up in Mode 2 configuration. Once the reset is issued,

all digital logic and configuration registers are set to the respective default states (see the Channel Configuration

Map and System Configuration Map sections for default values). Any conversion in process is aborted as soon

as a reset is issued. Data stored in the FIFO buffer are also reset. The channels and system registers must be

reconfigured.
