Management interface operation mode:
Pulldown – Lightly Managed Serial. CPU can
transmit/receive frames with the serial
interface.
Pullup – 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.
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).
EEPROM not installed.
Pullup: Not installed
Pulldown: Installed
Manufacturing Option. Must be pulled up.
