Zarlink Semiconductor Inc.
C3, D3, C2
TSTOUT[3:1]
Input (Reset Only)
Management interface operation mode:
000 – 16-bit parallel interface
001 – 8-bit parallel interface
010 – Serial with MII as Ethernet frame
transfer interface.
011 – Serial only. CPU can transmit/receive
frames with the serial interface.
111 – Unmanaged Serial. No CPU packet can
be transmit or received with the serial
interface. EEPROM can be used to configure
the device at bootup.
A one (1) indicates pullup. A zero (0)
indicates pulldown. TSTOUT[1] is the Least
Significant Bit (LSB).
C5, C4, D4
TSTOUT[6:4]
Input (Reset Only)
Device ID. Default address of the device for
serial interface. Up to 8 device can be sharing
the serial management bus with different
device ID.
A one (1) indicates pullup. A zero (0)
indicates pulldown. TSTOUT[4] is the Least
Significant Bit (LSB).
C6
