RPull

Pullup or pulldown resistor(2)

For pullup: VIN = VSS

For pulldown: VIN = VCC

kΩ

Input capacitance

VIN = VSS or VCC

(1)

Same parametrics apply to clock input pin when crystal bypass mode is used on XT1 (XIN) or XT2 (XT2IN).

(2)

Also applies to RST pin when pullup or pulldown resistor is enabled.

8.8 Inputs – Ports P1, P2, P3, and P4

t(int)

External interrupt timing(2)

Port P1, P2, P3, P4: P1.x to P4.x,

External trigger pulse duration to set interrupt flag

2.2 V, 3 V

(1)

Some devices may contain additional ports with interrupts. See the block diagram and terminal function descriptions.

(2)

An external signal sets the interrupt flag every time the minimum interrupt pulse duration t(int) is met. It may be set by trigger signals

shorter than t(int).

8.9 Leakage Current – General-Purpose I/O

MAX UNIT

Ilkg(Px.x)

High-impedance leakage current

See (1) (2)

1.8 V, 3 V

±50

(1)

The leakage current is measured with VSS or VCC applied to the corresponding pins, unless otherwise noted.

(2)

The leakage of the digital port pins is measured individually. The port pin is selected for input and the pullup or pulldown resistor is

disabled.

drop specified.

(2)

The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±100 mA to hold the maximum voltage

drop specified.
