NMON interface (continued)

The NMON control field is mapped to the lower four bits of the system NMON register DIO register address

0xA2.

For 10-Mbit/s monitoring, the NMON signals are provided as shown in Table 3 (NMON register option bits:

MONRXTX = X, MONWIDE = 0).

RX signals are latched and provided after a delay of one RX clock cycle. TX signals are the same as the TX

terminals (no latching) after a delay time.
