BQ78Z100: BCAST 旗標

HI 您好

關於在78Z100 參數文件中  未看到BCAST 說明

這個應用是什

但在BQ40Z50-R1 有說明

If the [HPE] bit is enabled, MASTER mode broadcasts to the host address are PEC enabled. If the [CPE]
bit is enabled, MASTER mode broadcasts to the smart-charger address are PEC enabled. The [BCAST]
bit enables all broadcasts to a host or a smart charger. When the [BCAST] bit is enabled, the following
broadcasts are sent:
• Charging Voltage() and Charging Current() broadcasts are sent to the smart-charger device address
(0x12) every 10 to 60 s.
• If any of the [OCA], [TCA], [OTA], [TDA], [RCA], [RTA] flags are set, the AlarmWarning() broadcast is
sent to the host device address (0x14) every 10 s. Broadcasts stop when all flags above have been
cleared.
• If any of the [OCA], [TCA], [OTA], [TDA] flags are set, the AlarmWarning() broadcast is sent to a smartcharger
device address every 10 s. Broadcasts stop when all flags above have been cleared.

在默認使用上我是關閉的

1.BQ78Z100 在I2C 默認下是開啟的

  功能是否跟BQ40Z50-R1 一樣 (因為是SMBS 才默認關閉)    但BQ78Z100 是沒有 [HPE] [CPE] 這旗標設置

2. BQ78Z100 若選擇關閉 BCAST  會不會影響 I2C 通訊

3. Q78Z100  BCAST   本身是虛設的?

Star Xu：

您好，BQ78Z100 没有找到BROADCAST mode的相关介绍，应该不支持BROADCAST mode
