Zarlink Semiconductor Inc.
It provides independent 2 bit wide (di-bit) transmit and receive data paths.
It uses TTL signal levels, compatible with common digital CMOS ASIC processes.
Table 5 - RMII Specification Signals
10.0 The Control Bus
The CPU Interface, or Control Bus, provides the communication path between the system CPU and all other key
components within the switch (i.e. the HISC). It operates in two modes: managed mode, where it utilizes an
external CPU, and unmanaged mode, where an external CPU does not exist.
In Managed mode, the CPU Interface provides the communication path between the systems’ external CPU and
the HISC, Frame Buffer Memory (SRAM) or another MDS212. See Figure 10.
Figure 10 - CPU Interface Configuration in Managed Mode
In unmanaged mode, the CPU Interface provides the communication path between the Switch Devices
and Flash Memory, and between any two MDS212 Switches. See Figure 11.
