Detailed Description

API for managing TRAPA events and handlers.

This API provides methods for setting and getting the installed handler for a particular TRAPA code.

TRAPA is an SH4 instruction which simply takes a code (0-255) and fires an exception event which transfers execution to the kernel so that it can then be handled in software.
