Note (1): The values may be overwritten by the Auto-Configure operation (See “Auto-Configuring Control Registers” on page 16 and Table 92 for details).
Note (1): ‘V’ is a version number. See “JTAG & AC-JTAG Operations” on page 53 for a note about the version number.
Note (2): 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 (3): Read value depends on status signal values. Value shown indicates ‘normal’ operation.
Note (4): The IEEE 802.3ae specification allows this to be all zeroes. A XENPAK (etc.) host can more readily determine where the NVR registers are if this value is zero.
Note (5): If IEEE 802.3ae (and default) setting for PCS Loopback, 180F’h. If PCS Loopback allowed, 1C0F’h. See Table 61 and Table 64.
