Bit 27 of RTCIO_TOUCH_PADn_REG

[apuder]

Hi,

I have been tracing a call to rtc_gpio_pullup_dis(GPIO_NUM_2). This leads to a call to rtcio_ll_pullup_disable where bit 27 is cleared of RTCIO_TOUCH_PAD2_REG. I checked the TRM for this register (Register 4.54) but for bit 27 it says "reserved". What am I missing here?

TIA,
AP

So, this is an example of "the code is the documentation." I guess this is a question for the Espressif folks: how much up to date is the TRM and when will the documentation catch up with the current hardware/software?
