Enable Debounce on SSI interface
Pullup – Enabled
Pulldown - Disabled
When enabled, DATAOUT is an open-drain
output; when disabled, DATAOUT is a
totem-pole output.
See “Synchronous Serial Interface (SSI)” on
page 133 for more details on debounce
timing.
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).
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).
