Freescale Semiconductor
Address:
A break interrupt causes exit from stop mode and sets the SBSW bit in
the break status register. See
The break status and control register contains break module enable and
status bits.
BRKE — Break Enable Bit
These registers control and monitor operation of the break module:

•
•
This read/write bit enables breaks on break address register matches.
Clear BRKE by writing a logic 0 to bit 7. Reset clears the BRKE bit.
