How can we drive the GPIO's of iMX280 to high impedance or tri-state? Can someone provide details of the GPIO configuration / settings?
Hi Manjunath
this is provided by HW_PINCTRL_DOEx register, from
sect.9.4.53 PINCTRL Bank 0 Data Output Enable Register
(HW_PINCTRL_DOE0) MCIMX28RM
For pins in bank 0 that are configured as GPIOs, a 1 in this register will enable the
corresponding bit value from HW_PINCTRL_DOUTxx register to be driven out the pin,
and a 0 in this register will disable the corresponding driver.
Best regards
igor
