Description

TDO: JTAG Test Data Output

98

F13

This pin output the serial data of the JTAG Test. The data on TDO is clocked out of the device on the fall-

ing edges of TCK. TDO is a high-Z output signal. It is active only when scanning of data is out. This pin

should be left float when unused.

TDI: JTAG Test Data Input

99

F12 This pin input the serial data of the JTAG Test. The data on TDI is clocked into the device on the rising

edges of TCK. This pin has an internal pull-up resistor and it can be left open.
