Enable housekeeping timed functions
Housekeeping is another periodic operation mode, which can be used to periodically perform operations such as oscillator calibrations,
PLL calibration, EE refresh, or temperature 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.
Setup registers descriptions:
Housekeeping Config- Set the Burst transmission parameters.
Housekeeping Interval- Set the time interval between Burst transmissions.
6.7.4.1. Housekeeping Config
The housekeeping configuration register is used to specify which tasks the AMIS-53000 should perform during a housekeeping cycle.
HK Interval Resolution: Used to specify the clock frequency for the housekeeping interval timer.
Wake: When enabled, the AMIS-53000 will enable the system clock output, and issue an interrupt to an external controller.
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 INT ADC Channels: The AMIS-53000 will do conversions on the battery voltage and temperature sensor. This can be
used as a method to periodically update the temperature compensation loop.
Read EXT ADC Channels: When enabled, the two external ADC inputs will be converted during a housekeeping cycle.
Cal PLL, RC, Kicker: Allows periodic calibration of the oscillators of the AMIS-53000.
