Hi,
I Iave a question regarding CP[n] pin of OMAP-L138.
As you know, PUPD_ENA register can enable internal pull-up or pull-down functionality for pin group CP[n].
For example, PUPD_ENA[2] register enables CP[2] pin group. AXR14/CLKR1/GP0[6] are all CP[2] pin group.
If PUPD_ENA register is set, is the internal pull-up/pull-down functionality of AXR14/CLKR1/GP0[6] signal enabled regardless of pin mux setting of AXR14/CLKr1/GP0[6]? I think the internal pull-up/pull-down is enabled even if its pin is set as AXR14.
Is my understanding right?
Also I would like to explain this functionality with the internal schematic of OMAP-L138. Could you give me the schematic ?
I appritiate your quick reply.
Best regards,
Michi
