Coldfire Exception processing

Hello,

I have a question on the exception processing of the Coldfire MCF5235 CPU.

The Coldfire Programmer's Reference Manual (Ch. 11, p. 11-1) states that "Coldfire v2 and v3 use an instruction restart exception model".
Does this mean that when I generate an access error with an operand fetch, after returning from the exception handler with RTE, the CPU
will retry the same instruction ?

TIA
