7.3.2.24 ColdFire Flash Module
The ColdFire Flash Control Module is capable of generating interrupts by the setting of the CBEIF or
CCIF bits in the CFMUSTAT. These interrupt sources, however, should not occur when the device is in a
low-power mode as long as no Flash operation was in progress when the low-power mode was entered.
When performing a program or erase operation on the Flash, if a command is active (CCIF = 0) when the
MCU enters a low-power mode, the command sequence monitor will perform the following:
7.3.2.25 BDM
Entering halt mode via the BDM port (by asserting the external BKPT pin) will cause the CPU to exit any
low-power mode.
7.3.2.26 JTAG
The JTAG (Joint Test Action Group) controller logic is clocked using the TCLK input and is not affected
by the system clock. The JTAG cannot generate an event to cause the CPU to exit any low-power mode.
Toggling TCLK during any low-power mode will increase the system current consumption.
7.3.3
The functionality of each of the peripherals and CPU during the various low-power modes is summarized
in
automatically assumes when the STOP instruction is executed and the LPCR[LPMD] field is set for the
particular low-power mode. Individual peripherals may be disabled by programming its dedicated control
bits. The wakeup capability field refers to the ability of an interrupt or reset by that peripheral to force the
CPU into run mode.

Summary of Peripheral State During Low-Power Modes
The state of any longword(s) being programmed, or any erase
pages/physical blocks being erased, is not guaranteed if the MCU enters
stop mode with a command in progress. Active commands are immediately
aborted when the MCU enters stop mode. Do not execute the STOP
instruction during program and erase operations.
