Description
This instruction pushes the program counter (PC) and condition-code register (CCR) onto the
stack, then sets the I bit to 1. If the extended control register (EXR) is valid, EXR is also saved
onto the stack, but bits I2 to I0 are not modified. Next execution branches to a new address given
by the contents of the vector address corresponding to the specified vector number. The PC value
pushed onto the stack is the starting address of the next instruction after the TRAPA instruction.
