Address Error Trap:
This trap is initiated when any of the following
circumstances occurs:
• A misaligned data word access is attempted.
• A data fetch from unimplemented data memory
• A data access of an unimplemented program
• An instruction fetch from vector space is

Stack Error Trap:
This trap is initiated under the following conditions:
• The Stack Pointer is loaded with a value which is

Oscillator Fail Trap:
This trap is initiated if the external oscillator fails and
operation becomes reliant on an internal RC backup.

all of Y space, and unimplemented Y
space includes all of X space.
5.3.2
It is possible that multiple traps can become active
within the same cycle (e.g., a misaligned word stack
write to an overflowed address). In such a case, the
fixed priority shown in Figure 5-2 is implemented,
which may require the user to check if other traps are
pending in order to completely correct the Fault.
‘Soft’ traps include exceptions of priority level 8 through
level 11, inclusive. The arithmetic error trap (level 11)
falls into this category of traps.
‘Hard’ traps include exceptions of priority level 12
through level 15, inclusive. The address error (level
12), stack error (level 13) and oscillator error (level 14)
traps fall into this category.
Each hard trap that occurs must be Acknowledged
before code execution of any type may continue. If a
lower priority hard trap occurs while a higher priority
trap is pending, acknowledged, or is being processed,
a hard trap conflict will occur.
The device is automatically reset in a hard trap conflict
condition. The TRAPR Status bit (RCON<15>) is set
when the Reset occurs, so that the condition may be
detected in software.
