Test Clock
This is the clock pin to sample the JTAG input data.
Test Data In
This line is for the JTAG input test data.
Test Data Out
This line is for the JTAG output test data.
Test Mode Select
This line lets you select between active and JTAG mode.
When in JTAG mode, the I/Os are serialized. Active mode
is for normal operation.
Test Port Reset
When asserted LOW, this signal resets the internal JTAG
controller. It does not reset the chip.
