The CPU starts a break interrupt by:
The break interrupt begins after completion of the CPU instruction in
progress. If the break address register match occurs on the last cycle of
a CPU instruction, the break interrupt begins immediately.
A break interrupt stops the timer counter.
The COP is disabled during a break interrupt when V
on the RST pin. For V
Characteristics.
Three registers control and monitor operation of the break module:
•
•
•
•
•
Loading the instruction register with the SWI instruction
Loading the program counter with $FFFC–$FFFD
($FEFC–$FEFD in monitor mode)
Break status and control register, BRKSCR
Break address register high, BRKH
Break address register low, BRKL
