Sets default link type for all IMA groups. Not used with variable rate facilities
0 = 25 ms (E1 mode)
1 = 50 ms
2 = 100 ms
3 = 200 ms
0 = 1 SRAM, Set to 0 for all M2852x devices
This field indicates the range of valid PHY addresses.
This field has different ranges depending on Product type:

This bit indicates whether the ATM UTOPIA bus is operating in 16 bit (high) or 8 bit (low) data
mode.
This bit is set high if a transition detector for IMA_RefClk detects a bad signal. This bit is active
high and is reset upon reading this address.
This bit indicates that a parity error has been detected on the Transmit ATM side UTOPIA bus.
This bit is active high and is reset upon reading this address.
Reserved.
This bit indicates that a parity error has been detected on the Receive PHY side cell bus. This bit
is active high and is reset upon reading this address.
0 = T1
1 = E1
