Logic "0" input current

µA

Input signal equals GND.

PSEL has an internal pull-up

resistor and during configuration

the current will be -350 µA.

Logic "1" input current

µA

Input signal equals VDD

DIO setup time

TX mode, minimum time DIO

must be ready before the positive

edge of DCLK. Data should be

set up on the negative edge of

DCLK.

DIO hold time

TX mode, minimum time DIO

must be held after the positive

edge of DCLK. Data should be

set up on the negative edge of

DCLK.
