Development Support
The processor enters into the debug mode state when at least one of the bits in the exception cause register
(ECR) is set, the corresponding bit in the debug enable register (DER) is enabled and debug mode is
enabled. When debug mode is enabled and an enabled event occurs, the processor waits until its pipeline
is empty and then starts fetching the next instructions from the development port. For information on the
exact value of machine status save/restore registers (SRR0 and SRR1) refer to
“Exceptions.”
When the processor is in debug mode the freeze indication is asserted thus allowing any peripheral that is
programmed to do so to stop. The fact that the CPU is in debug mode is also broadcast to the external world
using the value b11 on the VFLS pins.
The development port should read the value of the exception cause register (ECR) in order to get the cause
of the debug mode entry. Reading the exception cause register (ECR) clears all its bits.
23.3.1.3
The CPU enters the check stop state if the machine check interrupt is disabled (MSR[ME] = 0) and a
machine check interrupt is detected. However, if a machine check interrupt is detected when MSR[ME] =

Implementation specific data protection error
External interrupt, recognized when MSR[EE] = 1
Alignment interrupt
Program interrupt
Floating point unavailable exception
Floating point assist exception
Decrementer exception, recognized when MSR[EE] = 1
System call exception
Trace, asserted when in single trace mode or when in branch trace mode (refer to
“Trace Exception
Implementation dependent software emulation exception
Instruction breakpoint, when breakpoints are masked (BRKNOMSK bit in the LCTRL2 is clear)
recognized only when MSR[RI] = 1, when breakpoints are not masked (BRKNOMSK bit in the
LCTRL2 is set) always recognized
Load/store breakpoint, when breakpoints are masked (BRKNOMSK bit in the LCTRL2 is cleared)
recognized only when MSR[RI] = 1, when breakpoints are not masked (BRKNOMSK bit in the
LCTRL2 is set) always recognized
Peripherals breakpoint, from the development port, internal and external modules. are recognized
only when MSR[RI] = 1.
Development port non-maskable interrupt, as a result of a debug station request. Useful in some
catastrophic events like an endless loop when MSR[RI] = 0. As a result of this event the machine
may enter a non-restartable state, for more information refer to
Check Stop State and Debug Mode
The freeze signal can be asserted by software when debug mode is disabled.
