measurements taken with suitable decoupling capacitors across the power supply to suppress the transient
switching currents inherent in CMOS designs (see Section 2).
(2) Typical values are at md point of voltage range and at 25

(6) These limts are also applicable under the following conditions:
MCU RUN mode/SLOW mode/CAN active
MCU WAIT mode/SLOW mode/CAN active
MCU WAIT mode/CAN active
(7) These limts are also applicable under the following conditions:
MCU WAIT mode/SLOW mode/CAN asleep
(8) These currents are the summation of the MCU current + CAN current (I
DD
+ I
DD1
)
(9) Current injection is guaranteed but not tested.
Functionality of the MCU is guaranteed during injection of dc current up to the maximumspecified level.
The maximumspecified current for each port is the sumof the magnitudes of the currents on each side of the
individual port pins.
Some disturbance of the A/D accuracy is possible during an injection event and is dependent on board layout,
power supply decoupling and reference voltage decoupling configurations.
