0 = normal operation
1 = Center side is in Loop Back mode too long and the T1 timer has timeout.
0 = normal operation
1 = Center side does not receive reply frame from the Terminal side and the
0 = normal operation
1 = Link is down on port 1
0 = Link is up on port 1
Description
Reserved
(These two bits must be set to ‘00’ for normal operation)
Indicate support capability for “A-vendor” only. If Operating Mode (bits[1:0] of
this register) is set to “10”, these two bits are used by “A-vendor” to indicate
support for “extended mode”.
Operating Code
Operating Mode
Description
If Center MC sends the “Remote Command” in register 0x42h, this register
value will be used for M39-M32 of the Maintenance frame, instead of register
0x56h.
[AMM39:AMM32] = bits[7:0] of the KS8993F address byte if the Operating
Mode in register 0x4Ah bits[1:0] is set to “10”
others: Reserved
If Operating Mode (bits[1:0] of this register) is set to “10”, these two bits are
used to select one of the following Operating Codes:
Select between “normal mode” and “extended mode”, defined as follows:
10: Support “extended mode”
00: read reply
10: extended mode, MM24-MM47 (registers 0x55h to 0x57h) are
