TMS: JTAG Test Mode Select
The signal on this pin controls the JTAG test performance and is sampled on the rising edge
of TCK.
TRSTB: JTAG Test Reset (Active Low)
A low signal on this pin resets the JTAG test port.
This pin should be connected to ground when JTAG is not used.
TCK: JTAG 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 updated on the falling edge of TCK.
If TCK is idle at a low level, all stored-state devices contained in the test logic will indefinitely
retain their state.
TDI: JTAG Test Data Input
The test data are input on this pin. They are clocked into the device on the rising edge of
TCK.
TDO: JTAG Test Data Output
The test data are output on this pin. They are clocked out of the device on the falling edge of
TCK.
TDO pin outputs a high impedance signal except during the process of data scanning.
