Note (1): V’ is a version number. See “JTAG & AC-JTAG Operations” on page 53 for a note about the version number.
Note (2): Read values depend on status signal values. Values shown indicate ‘normal’ operation.
Note (3): If NVR load operation succeeds, will be overwritten by value loaded, see Table 22
Note (4): Default value depends on CX4/LX4 select LX4_MODE Pin Value. IEEE 802.3ae shows as R/W, but cannot write any other value.
Note (5): For rows with “A”, the default value may be overwritten by the Auto-Configure operation (See “Auto-Configuring Control Registers” on page 16 and Table 92
for details).
Note (6): IEEE 802.3 shows as R/W, but cannot write any other value than that set by LX4_MODE Pin.
