ESP8266EX 芯片技术规格书修改 ESP8266EX Chip Datasheet Amendments

PublishTime：2021-12-15

●变更原因:
■由于ESP8266EX 芯片的天线分集功能仅可通过GPIO16：XPD_DCDC 实现，而GPIO16 已被用作深度睡眠唤醒功能，因此决定在此次ESP8266EX 技术规格书的更新中删除栏目1.1：Wi-Fi主要特性，以及栏目3.4.1：Wi-Fi射频和基带中的天线分集功能。
●Reason for Change:
■The antenna diversity feature of ESP8266EX chips can only be enabled by GPIO 16: XPD_DCDC.However, the GPIO 16 is currently used for deep sleep wakeup. Antenna diversity is removed from section1.1, Wi-Fi Key Features and section 3.4.1, Wi-Fi Radio and Baseband of ESP8266EX chips in this update to the datasheet.
●变更内容:
■移除ESP8266EX 芯片的技术规格书栏目1.1 以及栏目3.4.1 中提及的天线分集功能。
●Proposed Change:
■Removing the antenna diversity feature mentioned by section 1.1 and section 3.4.1 in the datasheet of ESP8266EX chips.
