De scr ip tio n
MDC is the management data clock reference for the serial management
interface. A continuous clock stream is not expected. The maximum fre-
quency supported is 8.3 MHz.
MDIO is the management data. MDIO transfers management data in and out
of the device synchronously to MDC. This pin requires a pull-up resistor in a
range from 1.5 kohm to 10 kohm.

Boundary scan test data input.
Boundary scan test mode select input.
TMS contains an internal 150 kohm pull-up resistor.
Boundary scan test clock input.
TCK contains an internal 150 kohm pull-up resistor.
Boundary scan test reset input. Active low. TRSTn contains an internal 150
kohm pull-up resistor as per the 1149.1 specification. After power up, the
JTAG state machine should be reset by applying a low signal on this pin, or
by keeping TMS high and applying 5 TCK pulses, or by pulling this pin low by
a 4.7 kohm resistor.
Boundary scan test data output.
