Hi, 1. 20 mA for modem sleep is measured in test mode on the chip. "Max speed" means high CPU frequency. "Normal speed" means middle CPU frequency. "Slow speed" means low CPU frequency. CPU frequency can be changed during modem sleep in order to reduce current. 2. It is a feature in IDF. We can call...

The current on slow state is measured in test mode. This document means that the hardware of our chip does support this feature that reduces current when cpu works on slow state. But the IDF has not implemented the whole function yet. This function can not be found in our release notes of IDFv0.9~v2...
