Notes:

1

The pull-up structure is a passive high-side current source with a nom. 10µA current.

2

The passive pull-up current source as per note 1 on these parameter port pins is off, if the slave device is programmed with

I/O-configuration code 7 and a master data call is present.

Functional, Electrical and Timing Characteristics

All voltages are referenced to ground pin LTGN. Timing is valid for a quartz crystal frequency of 5.333MHz.
