Description
Reserved
(This bit must be set to ‘0’ for normal operation)
Read acknowledge.
This bit combines with bits [3:2] = ‘01’ in this register to select
between read request and read acknowledge.
reg. 74 bits [6,3,2] = ‘001’ : read request
reg. 74 bits [6,3,2] = ‘101’ : read acknowledge
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”.

others : Reserved
Description
Operating Code
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:
00 : read reply
01 : read request
10 : write reply
11 : write request
Operating Mode
Select between “normal mode” and “extended mode”, defined
as follows:
00 : normal mode, MM24-MM47 (registers 0x55h to 0x57h)
are used for My Model Info.
10 : extended mode, MM24-MM47 (registers 0x55h to 0x57h)
are mapped to Remote Command (registers 0x4Ah to 0x4Ch)
01 : reserved
11 : reserved
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 KSZ8893FQL address byte
if the Operating Mode in register 0x4Ah bits[1:0] is set to “10”
: Support “extended mode”
