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 CX2822X devices
This field indicates the range of valid PHY addresses.
This field has different ranges depending on Product type:
This bit is the current state of the signal ATMUTxAddr[4].
This bit is the current state of the signal ATMURxAddr[4].
Reserved
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
2 = Alternate T1 (1.544 Mbps payload)
3 = Alternate E1 (1.984 Mbps payload)
0: addresses 0x00–0x03 are valid
