19.1 Introduction
This section describes the break module, the monitor module (MON), and the monitor mode entry
methods.
19.2 Break Module (BRK)
This section describes the break module (BRK). The break module can generate a break interrupt that
stops normal program flow at a defined address to enter a background program.
Features of the break module include:
19.2.1 Functional Description
When the internal address bus matches the value written in the break address registers, the break module
issues a breakpoint signal to the system integration module (SIM). The SIM then causes the CPU to load
the instruction register with a software interrupt instruction (SWI). The program counter vectors to $FFFC
and $FFFD ($FEFC and $FEFD in monitor mode).
The following events can cause a break interrupt to occur:
When a CPU generated address matches the contents of the break address registers, the break interrupt
is generated. A return-from-interrupt instruction (RTI) in the break routine ends the break interrupt and
returns the microcontroller unit (MCU) to normal operation.

A CPU generated address (the address in the program counter) matches the contents of the break
address registers.
Software writes a 1 to the BRKA bit in the break status and control register.
