FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Wake-up Input Register (WUR)
The local wake-up inputs, L0, L1, L2, and L3 can be used in both Normal and Standby modes as port expander, as well as
and for waking up the SBC in Sleep or Stop modes. See Table 22.
The wake-up inputs can be configured separately, while L0 and L1 are configured together. Bits L2 and L3 are configured
together. See Table 23.
Table 24 provides Status bits data.
Timing Register (TIM1/2)
This register is composed of two registers:
1. TIM1–controls the watchdog timing selection as well as the window or timeout option. TIM1 is selected when bit D3 is 0.
Please see Table 25.
2. TIM2–is used to define the timing for the cyclic sense and forced wake-up function. TIM2 is selected when bit D3 is read
operation it is not allowed in either TIM1 or TIM2 registers. Please see Table 27.

Description
L3WU
Wake-up Occurred (Sleep/Stop Modes), Logic State on Lx (Standby/Normal Modes)
L2WU
L1WU
L0WU
Notes: Status bits have two functions. After SBC wake-up, they indicate the wake-up source (Example: 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 WD timeout occurs before the first reading of the WUR register, the LXxWU bits are reset. This can occur
only if SBC was in Stop mode.
