State Machine Description
Nostop = Nostop bit = 1
!Nostop = Nostop bit = 0
BATFAIL = Batfail bit = 1
!BATFAIL = Batfail bit = 0
VDD Over-temperature = VDD thermal shutdown occurs
VDD LOW = VDD below reset threshold
VDD LOW > 100 ms = VDD below reset threshold for more than 100 ms
Watchdog: Trigger = TIM1 subregister write operation
VSUP > BFew = VSUP > Battery Fail Early Warning (6.1 V typical)
Watchdog: Timeout = TIM1 register not written before watchdog timeout period
expired, or watchdog written in incorrect time window if watchdog window
selected (except Stop mode). In Normal Request mode, timeout is 355 ms
p2.2 (350 ms p3) ms.
SPI: Sleep = SPI write command to MCR register, data sleep
SPI: Stop = SPI write command to MCR register, data stop
SPI: Normal = SPI write command to MCR register, data normal
SPI: Standby = SPI write command to MCR register, data standby
