1.4 Interfaces
This section lists the interfaces in the DMC-620.
The DMC-620 has the following external interfaces:
- A system interface to provide read and write access to or
from a master that supports either the CHI-A or CHI-B protocol.
- An APB3 programmers interface to program and control the DMC-620.
- A DFI-compatible PHY interface to transfer data to and from the external
memory.
- A profile and debug interface.
- A low-power clock control interface that uses the Q-Channel
protocol. See Q-Channel interface.
- An abort interface that is a four-phase request and acknowledge handshake.
The abort interface can be used to recover from a livelock when DRAM or PHY
fails.
- User I/O ports.
- A set of interrupts that are used to report operational events and
detected faults.
