TRST: Test Reset (Active Low)
A low signal on this pin resets the JTAG test port. This pin is a Schmitt-triggered input with an internal pull-up
resistor. It must be connected to the RESET pin or ground when JTAG is not used.
TMS: Test Mode Select
The signal on this pin controls the JTAG test performance and is sampled on the rising edge of TCK. This pin
is a Schmitt-triggered input with an internal pull-up resistor.
TCK: Test Clock
The clock for the JTAG test is input on this pin. TDI and TMS are sampled on the rising edge of TCK and TDO
is clocked out of the device on the falling edge of TCK. This pin is a Schmitt-triggered input with an internal
pull-up resistor.
TDI: Test Input
The test data is sampled at this pin on the rising edge of TCK. This pin is a Schmitt-triggered input with an
internal pull-up resistor.
TDO: Test Output
The test data are output on this pin. It is updated on the falling edge of TCK. This pin is High-Z except during
the process of data scanning.
