6.17 Error Signaling Module
The Error Signaling Module (ESM) manages the various error conditions on the TMS570 microcontroller.
The error condition is handled based on a fixed severity level assigned to it. Any severe error condition
can be configured to drive a low level on a dedicated device terminal called nERROR. The nERROR can
be used as an indicator to an external monitor circuit to put the system into a safe state.
6.17.1 ESM Features
The features of the ESM are:
128 interrupt/error channels are supported, divided into three groups
64 channels with maskable interrupt and configurable error pin behavior
32 error channels with nonmaskable interrupt and predefined error pin behavior
32 channels with predefined error pin behavior only
Error pin to signal severe device failure
Configurable time base for error signal
Error forcing capability
6.17.2 ESM Channel Assignments
The ESM integrates all the device error conditions and groups them in the order of severity. Group1 is
used for errors of the lowest severity while Group3 is used for errors of the highest severity. The device
response to each error is determined by the severity group it is connected to. Table 6-31 lists the channel
assignment for each group.
