Description
TDO: JTAG Test Data Output
98
F13
The serial data of the JTAG test is output on this pin. The data on TDO pin is clocked out of the device on
the falling edges of TCK. TDO is a high impedance output signal. It is active only when scanning of data is
over. This pin should be left float when unused.
TDI: JTAG Test Data Input
99
F12 The serial data of the JTAG test is input on this pin. The data on TDI pin is clocked into the device on the
rising edges of TCK. This pin has an internal pull-up resistor and it can be left disconnected.
