Theory of operation
Figure 21. Timing for writing configuration and mode bits
32/46
The same procedure should be applied for the mode signals, but in this case the 6-bits
address must be taken from the
The lsb of command is also called EXE bit because instead of data bit value, the
corresponding serial clock pulse is used to generate the necessary latching signal. In this
way the writing mechanism does not need the measurement clock in order to operate, which
makes the operation of CFGI module of STPM1x completely independent from the rest of
the device logic except from the signal POR.
Commands for changing system signals should be sent during active signals SCS and SYN-
NP as it is shown in the
active signals SCS and SYN-NP.
