4.6 Switch Configuration Options

The DP83869EVM includes a 4-pin dip switch (S1), which can be used for various test modes and feature displays. Some of the switch settings can also be used with the USB-2-MDIO GUI for additional control. Except for switch mode 15, all switch modes are hard-coded and can be used without USB-2-MDIO or any other serial com port. Refer to Table 4-11 for switch configurations and LED outputs. For each switch, PU is 1 and PD is 0.

To begin reading data continuously with USB-2-MDIO: Read the register address "OPEN"
To stop reading data continuously with USB-2-MDIO: Read the register address "STOP"
(1) During the loop for Mode 15, USB-2-MDIO is not operational. However, other serial port terminals (that is, PuTTY) can be used to view real-time data.

When running switch mode 15, data is constantly sent to the serial port. USB-2-MDIO is not capable of supporting the constant read feature. However, other serial port terminals, that is, PuTTY, can be used. When using a serial port terminal, copy and paste data. Do not enter in the data slowly, because the firmware executes as soon as the data is received.

To load a list of registers to read data from, follow this data format:

##LOADAAAAB/

  • ## = Two digit PHY ID expressed in decimal form
  • LOAD = the string 'LOAD' indicates to the MC to add a register to the list
  • AAAA = Four character Register Address to read data from in hex form (that is, Read register 0x133h, set AAAA = 0133)
  • B = use '*' for an extended access read and '=' for a direct access read
  • / = end string with '/'

For example, to load register 0x462h with PHY_ID = 1 with extended access, copy and paste the following command into a serial com terminal: 01LOAD0462*/

To start reading data, continuously copy and paste the following into the serial com terminal: OPEN

To stop reading data, continuously copy and paste the following into the serial com terminal: STOP

Note: The OPEN and STOP commands are in no particular position, so the designer can copy OPENSTOP and paste into the serial com terminal once to start reading data and then paste again to stop reading data, for example.
Note: When the read loop is stopped, the list of registers to read is cleared.
