denotes priority
“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
100 ms
“W/D: Trigger” means TIM1 register write operation.
VSUP > BFew means VSUP > Battery Fall Early Warning (6.1 V typical)
“W/D: timeout” means TIM1 register not written before W/D timeout period
expired, or W/D written in incorrect time window if window W/D selected
(except stop mode). In normal request mode timeout is 355 ms p2.2 (350 ms
p3)ms.
“SPI: Sleep” means SPI write command to MCR register, data sleep
“SPI: Stop” means SPI write command to MCR register, data stop
“SPI: Normal” means SPI write command to MCR register, data normal
“SPI: Standby” means SPI write command to MCR register, data standby
Note 1: these 2 SPI commands must be send in this sequence and
consecutively.
Note 2: if W/D activated
