I am seeking assistance on the Arm forum to understand how the 1-bit ACTIVE signal in the Arm® Power Policy Unit Architecture Specification corresponds to different power modes, as mentioned in section 3.3.2 Q-Channel PPU Power Modes Transitions. This section discusses various transitions between power modes, but given that the ACTIVE terminal of the Q-channel interface is a 1-bit signal, how does it map to different power modes?
Any insights or explanations on this matter would be greatly appreciated. Thank you.
