23.5.2 Stop Mode
23.6 Break Module Registers
23.6.1 Break Status and Control Register
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
Address:
A break interrupt causes exit from stop mode and sets the SBSW bit in
the break status register.
These registers control and monitor operation of the break module:
The break status and control register (BRKSCR) contains break module
enable and status bits.
BRKE — Break Enable Bit
Reset:
Read:
Write:

•
•
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.
