A stack overflow in a safety application may result in a catastrophic software crash due to data corruption, lost return addresses, or both. Hence, it is important to detect an impending stack overflow. The enhanced bus comparator (EBC) unit in the ERAD module can monitor the internal address and data buses, and trigger the RTOSINT interrupt when a specified bus and mask matches a specified value. Hence, the basic approach for detecting stack overflow will be to configure the EBC unit to trigger an interrupt when the data write address bus falls within some range prior to the end of a stack. Since this memory is reserved for stack usage only, a data write within the specified address range indicates that the stack usage is approaching its allocated size limit. Detection of an impending stack overflow triggers a maskable interrupt. Programmed error response and any necessary software requirements are defined by the system integrator.
