NOTE: The test pin should be protected from potential EMI
and ESD voltage spikes. This may require a smaller
external pulldown resistor in some applications.
x = Bit identifier, 4 to 7 for port P1
During programming activity and during blowing
the fuse, the pin TDO/TDI is used to apply the test
input for JTAG circuitry.
