Bit [0]:
Store configuration
(Default = 0)
Write ‘1’ followed by ‘0’ to store configuration into external EEPROM
Bit[1]:
Store configuration and reset
(Default = 0)
Write ‘1’ to store configuration into external EEPROM and reset chip
Bit[2]:
Start BIST
(Default = 0)
Write ‘1’ followed by ‘0’ to start the device’s built-in self-test. The result is found in the DCR register.
