Clarification required for internal pull-up in CHIP_EN pin

[hfcheng]

Hi Espressif team,

In the English version of Hardware User Guide (0B-ESP8266__Hardware_User_Guide__EN_v1.1.pdf), Section 2.2.2, it is said "There is an internal pull-up in the CHIP_EN pin, so no external pull-up is needed.". However we are not able to find the correspond Chinese string in the Chinese version (0B-ESP8266__Hardware_User_Guide__CN_v1.1.pdf) of the document, which sort of making us a bit confused.

Could you confirm whether the internal pull-up does exist or not?

Best Regards.

Dear Sir,

Sorry for the mistake in the english version of Hardware_User_Guide and we will modify it ASAP.

CHIP_EN has no internal pull-up resistor and it cannot be dangled.

EXT_RSTB has internal pull-up resistor and it can be left dangled when it is not used.

Any more questions, please let us know.

Thanks.
