Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only,

and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is

not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:

Note 3:

Stop mode current measured with XTAL1 = RST =

Note 4:

Note 5:

Applies to port pins when they are used to address external memory or as CAN interface signals.

Note 6:

This measurement reflects the port during a 0-to-1 transition in I/O mode. During this period a one-shot circuit drives the ports hard

for two clock cycles. If a port 4 or 5 pin is functioning in memory mode with pin state of 0 and the SFR bit contains a 1, changing

the pin to an I/O mode (by writing to P4CNT) will not enable the 2-cycle strong pullup. During Stop or Idle mode the pins switch to

I/O mode, and so port 2 and port 1 (in nonmultiplexed mode) will not exhibit the 2-cycle strong pullup when entering Stop or Idle

mode.

Note 7:

Port 3 pins 3.6 and 3.7 have a stronger than normal pullup drive for one oscillator period following the transition of either the

RD or

WR from a 0-to-1 transition.

Note 8:

This is the current required from an external circuit to hold a logic low level on an I/O pin while the corresponding port latch bit is

set to 1. This is only the current required to hold the low level; transitions from 1 to 0 on an I/O pin also have to overcome the

transition current.

Note 9:

Ports 1(in I/O mode), 3, 4, and 5 source transition current when being pulled down externally. It reaches its maximum at

approximately 2V.
