The wake-up inputs can be configured almost separetly, where L0 and L1 are configured together and L2 and L3 are
configured together.
Control bits:
.
Status bits:
note: Status bits have two functions. After SBC wake up, they indicate the wake up source (exemple: L2WU set at 1 if wake up
source is L2 input). After SBC wake and once the WUR has been read, status bits indicates the real time state of the Lx inputs (1
mean Lx is above threshold, 0 means that Lx input is below threshold).
If after a wake up from Lx input, a W/D timeout occurs before the first reading of the WUR register, the LxWU bits are reset.
This can occurs only if SBC was in stop mode.
7.1.6
TIM registers
Description: This register is splitted into 2 sub registers, TIM1 and TIM2.
TIM1 controls the watchdog timing selection as well as the window or time out option. TIM1 is selected when bit D3 is 0.
TIM2 is used to define the timing for the cyclic sense and forced wake up function. TIM2 is selected when bit D3 is 1.
No read operation is allowed for registers TIM1 and TIM2
