Hi,
I have a few questions from my customer about internal pull-up(IPU) and internal pull-down(IPD).
Q1) How to enable / disable IPU/IPD at each pin?
I could not find any registers for this purpose.
IPU/IPD are enabled all the time?
Q2) If answer to Q1 is “Yes”.
IPU/IPD are enabled even the pin is configured as output?
For example, EMIF pins are input/output/HiZ based on control signal truth table.
IPU/IPD are enabled regardless I/O mode?
(ideally IPU/IPD should be enabled only when HiZ)
Thanks and regards,
Koichiro Tashiro
