S/UNI-IMA-4 Telecom Standard Product Data Sheet  
Released  
10.7.3 Registers  
The Register Memory Map in Table 5 shows where the normal mode registers are accessed. The  
resulting register organization is split into sections: Master configuration registers, TC Layer,  
Clock/Data Interface and IMA Sublayer registers.  
On power up, the S/UNI-IMA-4 requires configuration. For proper operation, register  
configuration is necessary in order to program addresses for the Any-PHY ports, enable the  
SDRAM, configure the Line interface and chose IMA or TC mode for each link/group. By  
default, interrupts will not be enabled.  
The Line-side-access defaults to a disabled state; this results in all line side output pins being  
tristated. When the Clock/Data line mode is chosen, the pins will be enabled.
