GPIO pullup / pulldown
Posted: Fri Apr 13, 2018 9:48 am
Hi,
I have read that GPIO_34 - GPIO_39 have no pullup / pulldown resistors no matter if they are connected to RTC_MUX or IO_MUX. Is this true?
Are pins RTC_6 - RTC_9 affected by 3.6 bug too? And if so, which register (XTAL_32 / TOUCH) should I use for RTC pins 8 (XTAL_32_K_N / TOUCH8) and 9 (XTAL_32_K_P / TOUCH9) to work around 3.6 bug ( = set pullup / pulldown for GPIO_32 and GPIO_33)? Both registers allow setting up pullup / pulldown.
Thank you.
