Hi,
I have a question about AM335x unused pin.
The following pins are already routed to the external device but now these pins doesn't need.
Even if High/Low signal is input externally to these pins, I want to prevent undesired AM335x operation. So, I want to disable these pins.
By the way, there are no external pullup/down routed.
-V2 "LCD_DATA12"pin
-U18 "GPMC_BEn1" pin
-T10 "GPMC_AD9" pin
-T17 "GPMC_WAIT0"pin
I'm thinking following method.
////////////////////////////////////////////////////////////////////////////////
Configure each conf_<module>_<pin> Register as follow:
bit6: Select between faster or slower slew rate => 0: Fast
bit5: Input enable value for the PAD => 0: Receiver disabled
bit4: Pad pullup/pulldown type selection => 0: Pulldown selected
bit3: Pad pullup/pulldown enable => 0: Pullup/pulldown enabled
bit2-0: mux select => Mode7(GPIO)
Cofigure GPIO_OE Register appropriate bit to 0( configure GPIO as output)
////////////////////////////////////////////////////////////////////////////////
Is these configuration correct? Is there any additional settings?
best regards,
g.f.
