Other Parts Discussed in Thread: DA8XX, OMAPL138

Hi,

Please let me confirm about IPU/IPD behavior of pins when POR is being activated.

DA8xx datasheet says that all pins (except /RESETOUT) are tri-stated during POR . At this point, IPU/IPD is being activated ?

Hello Kawada,

Yes, all the pins are tri-stated during POR since the pinmux registers are default to 0 during POR.

The IPU/IPD is activated during POR and its state will be the same during and after reset. Also please note that No configure-ability on PU/PD on OMAPL137 unlike OMAPL138. Whether the pin has IPU or IPD can be deduced from the terminal function table.

Senthil
