Clocks and Power Control
During the power down sequence PORESET needs to be asserted while VDD, NVDDL, and QVDDL are
at a voltage greater than or equal to 2.5 V. Below this voltage the power supply chip can be turned off.
If the turn-off voltage of the power supply chip is greater than 0.74 V for the 2.6-V supply and greater than
0.8 V for the 5-V supply, then the circuitry inside the MPC561/MPC563 will act as a load to the respective
supply and will discharge the supply line down to these values. Since the 2.6-V logic represents a larger
load to the supply chip, the 2.6-V supply line will decay faster than the 5-V supply line.

VDDH ≥ QVDDL - 0.5 V
VDDA can lag VDDH, and VDDSYN can lag QVDDL, but both must be at a valid level before resets are negated.
If keep-alive functions are NOT used, then when system power is on: KAPWR = QVDDL ± 0.1 V; KAPWR ≤ 2.7 V
If keep-alive functions ARE used, then KAPWR = QVDDL = NVDDL = 2.6 V ± 0.1 V when system power is on
KAPWR = 2.6 V ± 0.1 V when system power is off. IRAMSTBY should be powered prior to the other supplies. If
IRAMSTBY is powered at the same time as the other supplies, it should be allowed to stabilize before PORESET
is negated. Normal system power is defined as QVDDL = VDD = VDDF = VDDSYN = KAPWR = 2.6 ± 0.1 V and
VDDA = VDDH = VFLASH = 5.0 ± 0.25 V. Flash programming requirements are the same as normal system
power. VFLASH should always be 5.0 ± 0.25 V. Note: Flash is not implemented on the MPC561.
Do not hold the 2.6-V supplies at ground while VDDH/VDDA is ramping to 5 V.
If 5 V is applied before the 2.6-V supply, all 5-V outputs will be in indeterminate states until the 2.6-V supply
reaches a level that allows reset to be distributed throughout the device If 5 V is applied before the 2.6-V supply,
all 5-V outputs will be in indeterminate states until the 2.6-V supply reaches a level that allows reset to be
distributed throughout the device
