Function
Enable housekeeping timed functions
Housekeeping is another periodic operation mode, which can be used to periodically perform operations such as oscillator calibrations,
re compensation. It can also be used to periodically wake an external host controller to allow it
to perform whatever tasks it may need to. The housekeeping configuration register contains the options to specify what is to occur
during a housekeeping cycle, and the housekeeping interval timer is used to control how frequently the wake-up occurs.
Register descriptions:
Housekeeping Config
- Sets the tasks for the housekeeping function
ets the time interval between times the AMIS-53050 wakes to perform the housekeeping function
Housekeeping Interval
- S
during a Housekeeping cycle.
HK Interval Resolution:
Used to specify the clock frequency for the housekeeping interval timer
Wake:
enabled, the AMIS-53050 will enable the system clock output, and issue an interrupt to an external controller.
Read INT ADC Channels:
The AMIS-53050 will do conversions on the battery voltage and temperature sensor. This can be
used as a method to periodically update the temperature compensation loop.
C Channels:
When enabled, the two external ADC inputs will be converted during a housekeeping cycle.

Housekeeping Config
The Housekeeping configuration register is used to specify which tasks the AMIS-53050 should perform
When
Write EE:
This option is used to store the values of any calibrations that may have been performed during housekeeping.
The entire working register bank will be written to EE.
Read EXT AD
Cal PLL, RC, Kicker:
Allows periodic calibration of the oscillators of the AMIS-53050.
