Storage Control Instructions
Storage control instructions mtsr, mtsrin, mfsr, mfsrin, dcbi, tlbie, tlbia, and tlbsync are not implemented
by the MPC561/MPC563.
3.15.4
Exceptions
The following paragraphs define the types of OEA exceptions. The exception table vector defines the
offset value by exception type. Refer to
3.15.4.1
System Reset Exception and NMI (0x0100)
A system reset exception occurs when:
•
Any reset signal is asserted: PORESET, HRESET, or SRESET
•
An internal reset is requested, such as from the software watchdog timer
Settings caused by reset as shown in
A non-maskable interrupt (NMI) occurs when the IRQ0 is asserted and the following registers are set.

IP depends on internal data bus configuration word; ME is unchanged.
DCMPEN is set according to (BBCMCR[EN_COMP] AND
BBCMCR[EXC_COMP]). All other bits are cleared

Description
Save/Restore Register 0 (SRR0)

All
Set to the effective address of the next instruction the
processor executes if no interrupt conditions are present
Save/Restore Register 1 (SRR1)

Cleared to 0
10:15
Cleared to 0
Other
Loaded from bits [16:31] of MSR. In the current
implementation, bit 30 of the SRR1 is never cleared, except by
loading a zero value from MSR[RI]
