Hi Fabio,

Hm, in the RM for i.MX233, page 1480 and above
(http://cache.freescale.com/files/dsp/doc/ref_manual/IMX23RM.pdf)
I can only find definitions like
"Set this bit to one to _disable_ the internal pad keeper and _enable_
the internal pull up resistor..." or for EMI pads at bank 3
"Set this bit to one to _disable_ the internal keeper"
(without a note about pull ups).

Could you please link me to your reference where the reverse
definition comes from?

Best regards,
Michael
