MSP430 VCC in volts
Operating voltage available at device terminals.
None – units always in volts.
none
No accuracy is specified for this measurement!
This value is intended to be used for informational
purposes only and should not be used for control.
Minimum operating voltage experienced by device at
terminals since last reset of operating voltage
parameters.
User can reset as desired using method described in
item below.
Backup once each 8 hour period
Displays time since last minimum operating voltage
event in minutes.
User can reset as desired using method described in
item below.
Update every 8 hour.
Causes "Min Op Voltage" to be set to 32 volts and
"Time Since Last Event" to be reset to zero. Within a
short period of time "Min Op Voltage" will assume
operating voltage value.
User actuates as desired.
Sensor MCU Supply voltage in volts
Total number of power-ups experienced by the device.
None – initialized to zero prior to leaving factory.
The count is stored in NVM.
Displays time since last power cycle event happened in
minutes.
None.
The information is stored in NVM at every 8 hours of
continuous device operation.
