4 Peripherals
4.1 Error Signaling Module (ESM)
The Error Signaling Module (ESM) is used to indicate a severe device failure via interrupts and the
external ERROR pin. The error pin is normally used by an external device to either reset the controller
and/or keep the system in a fail safe state.
The ESM module consists of three error groups with 32 inputs each. The generation of the interrupts and
the activation of the ERROR Pin is shown in the following table. The next table shows the ESM error
sources and their corresponding group and channel numbers.
Table 4-1. ESM Groups
Error Group Interrupt, Level Influence on ERROR pin
Group1 maskable, low/high configurable
Group2 non-maskable, high fixed
Group3 none, none fixed
