Table 2. Configuration and Control Signals
Hardware Chip Mode Select.
The CMODE inputs are used for hardware configuration of the various operating
modes of the PHY. Each pin has multiple settings, each of which is established by
an external 1% resistor tied to GND or VDD33A. See
figuration Using CMODE Pins”
pins.
Hardware Chip Reset.
RESET is an active low input. When asserted, it powers down all of the internal ref-
erence voltages and the PLLs. It resets all internal logic, including the DSPs and the
MII Management Registers.
Hardware reset is distinct from soft reset which only resets the port to accept new
configuration based on register settings.
Transmit Disable or Software Reset.
When asserted, it places the PHY in a low power state, which includes disabling the
SerDes interface. Although the device is powered down, non-volatile, Serial Man-
agement Interface registers retain their values.
TXDIS and SRESET are simply two names for the same function. The assertion
state (active high or low respectively) of this input pin is determined by the value of
Extended MII Register 21E.15 'SFP MODE' set at startup using Hardware Configu-
ration or via the EEPROM interface. Refer to
