15.2.2.5 Break Flag Control Register
The break control register (BFCR) contains a bit that enables software to clear status bits while the MCU
is in a break state.
Address: $FE03
Bit 7

Figure 15-8. Break Flag Control Register (BFCR)
BCFE — Break Clear Flag Enable Bit
This read/write bit enables software to clear status bits by accessing status registers while the MCU is
in a break state. To clear status bits during the break state, the BCFE bit must be set.
1 = Status bits clearable during break
0 = Status bits not clearable during break
15.2.3 Low-Power Modes
The WAIT and STOP instructions put the MCU in low power- consumption standby modes. If enabled,
the break module will remain enabled in wait and stop modes. However, since the internal address bus
does not increment in these modes, a break interrupt will never be triggered.
15.3 Monitor Module (MON)
This subsection describes the monitor module (MON) and the monitor mode entry methods. The monitor
allows debugging and programming of the microcontroller unit (MCU) through a single-wire interface with
a host computer. Monitor mode entry can be achieved without use of the higher test voltage, V
long as vector addresses $FFFE and $FFFF are blank, thus reducing the hardware requirements for
in-circuit programming.
Features include:
Normal user-mode pin functionality on most pins
One pin dedicated to serial communication between MCU and host computer
Standard non-return-to-zero (NRZ) communication with host computer
Execution of code in random-access memory (RAM) or FLASH
FLASH memory security feature
FLASH memory programming interface
Use of external 9.8304 MHz oscillator to generate internal frequency of 2.4576 MHz
Simple internal oscillator mode of operation (no external clock or high voltage)
Monitor mode entry without high voltage, V
$FF)
Standard monitor mode entry if high voltage is applied to IRQ
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH difficult for
unauthorized users.
