The ERR_O output of the MAIN Domain ESM0 drives the SOC_SAFETY_ERRORn pin directly to indicate a MAIN Domain safety error condition to an external device. The ESM0 ERR_O error output is also connected to the MCU_ESM0 as an error event input. Both Level and PWM Mode are supported on the SOC_SAFETY_ERRORn output signal if the ESM0 ERR_O is not monitored by MCU_ESM0. However, only Level Mode is allowed if the ESM0 ERR_0 error signal is actively monitored by the MCU_ESM0 module.
The MCU_ESM0 ERR_O error output is connected to the WKUP_ESM0 as an error event input, but it is not directly connected to a Device pin. Only Level Mode is allowed for the MCU_ESM0 ERR_0 error output.
The ERR_O output of WKUP_ESM0 drives the MCU_SAFETY_ERRORn pin directly to indicate a WKUP Domain safety error condition to an external device. This pin can also indicate MCU Domain and MAIN Domain safety error conditions via daisy-chaining of the Device ESM modules, provided that the Events corresponding to those daisy-chained ERR_O outputs are enabled.
Figure 5-25 describes the integration of the ESM Modules in the Device.
