3.4 MPC Q-Channels

The MPC provides two Q-Channel interfaces. You can use one channel for clock control and the other channel for power control, which enables the MPC to indicate when it requires clock and power.

Both Q-Channels implement the low-power interfaces that the AMBA® Low Power Interface Specification, Arm® Q-Channel and P-Channel Interfaces describes.

The presence of a synchronizer on the clk_qreqn and pwr_qreqn inputs of the Q-Channels is configurable, by using the QCLK_SYNC_EN and QPWR_SYNC_EN parameters.
