Original question:

LAUNCHXL-CC1352R1: Power mode切換在 Standby mode時, 是否能由sensor controller 控制I2C工作?

LAUNCHXL-CC1352R1: Sensor controller運作在Active mode時, MCU是否只能進入Idle mode, 無法進入Standby mode?

根據CC13x2, CC26x2 SimpleLink Technical Reference Manual p.514

MCU要進入Standby mode, 需要AUX運作在low-power mode時才行

所以當sensor controller運作在Active mode時, MCU是否只能進入Idle mode, 無法進入Standby mode?

若sensor controller要使用I2C master(bit-banged), 由下圖可知, 必須操作在Active mode下才能執行

意即MCU只能在Idle mode時, 才能用sensor controller來運作I2C master(bit-banged), 此結論是否正確?
