MF is the multiplication factor in the PLPRCR register (refer to
Reset-Control Register
C.3
C.3.1
Traces connecting capacitors, crystal, resistor should be as short as possible. Therefore, the components
(crystal, resistor and capacitors) should be placed as close to the oscillator pins of the MPC561/MPC563
as possible.
The voltage to the VDDSYN pin should be well regulated and the pin should be provided with an
extremely low impedance path from the VDDSYN filter to the VDDSYN pad.
The VSSSYN pin should be provided with an extremely low impedance path in the board. All the filters
for the supplies should be located as close as possible to the chip package. It is recommended to design
individual VSSSYN plane to improve VSSSYN quietness.
C.3.2
The traces from the oscillator pins and PLL pins of the MPC561/MPC563 should be guarded from all other
traces to reduce crosstalk. It can be provided by keeping other traces away from the oscillator circuit and
placing a ground plane around the components and traces.
C.3.3
IRAMSTBY is the data retention power supply for all on-board RAM arrays (CALRAM, DPTRAM,
DECRAM). It has a shunt regulator circuit to divert excess current to ground in order to regulate voltage
on the IRAMSTBY power supply pin. IRAMSTBY should be connected to a positive power supply, via a
resistor, and bypassed by a capacitor to ground as shown in
