Active current measured with 40MHz clock source on XTAL1, V_CC = RST = 5.5V, all other pins disconnected.
Idle mode current measured with 40MHz clock source on XTAL1, V_CC= 5.5V, RST = EA = V_SS, all other pins disconnected.
Stop mode current measured with XTAL1 = RST = EA = V_SS, V_CC = 5.5V, all other pins disconnected.
RST = V_CC. This condition mimics operation of pins in I/O mode.
Applies to port pins when they are used to address external memory or as CAN interface signals.
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.
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.
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.
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.
Specifications to -40°C are guaranteed by design and not production tested.
