Configuration bit map (continued)
As indicated above, the STPM10 includes 56 CFG bits. The CFG bits are not retained when
the STPM10 supply is not available and they are cleared when a POR occurs, but they are
not cleared when a remote reset command (RRR) is sent through SPI.
Normally, some of these bits must be loaded during power-up of the application. From the
microcontroller, it could also reload the configuration and calibration values after power-on
restart.
Mode signals
The STPM10 includes 8 mode signals located in the DFP data record. 3 of these are used
only for internal testing purposes while 5 are useful to change some of the operations of the
STPM10. The mode signals are not retained when the STPM10 supply is not available and
they are cleared when a POR occurs, but they are not cleared when a remote reset
command (RRR) is sent through SPI.
The mode signals bit can be written using the normal writing procedure of the SPI interface
