14.2. Register description
The register descriptions are presented here in ascending order of Register Address. Some registers carry several individual
data fields of various sizes; from single-bit values (e.g. flags), upwards. Some data fields are spread across multiple
registers. Unused bits are 'don't care' and writing either 0 or 1 will not affect any function of the device. After power on reset
the registers will have the values indicated in the tables "Reset" column.

Indicates if an EEPROM was detected at startup
Indicates if an XTAL was detected at startup
Enabled the clock output on CKOUT pin
Is set to 1 when SX8722 loaded its configuration from the
EEPROM at startup.
When set to 1 his bit activates the Sleep mode of the SX8722.
Setting pin SLEEP to 1 has the same effect.
When set to 1 his bit activates the Shutdown mode of the
SX8722. Setting pin SHUT to 1 has the same effect.
This flag shows if the SX8722 clock has been successfully
calibrated.
Sets the logical condition for alarm 1 on (0 = OR, 1 = AND)
Sets the logical condition for alarm 1 off (0 = OR, 1 = AND)
Sets the logical condition for alarm 2 on (0 = OR, 1 = AND)
Sets the logical condition for alarm 2 off (0 = OR, 1 = AND)
Configuration 4 enabling
