State machine description:
“Nostop” means Nostop bit = 1
“! Nostop” means Nostop bit = 0
“BATFAIL” means Batfail bit = 1
“! BATFAIL” means Batfail bit = 0
“VDD1 over temperature” means VDD1 thermal shutdown occurs
“VDD1 low” means VDD1 below reset threshold
“VDD1 low > 100 ms” means VDD1 below reset threshold for more than
“W/D: Trigger” means TIM1 register write operation.
