Terminal Functions
PIN NAME
DESCRIPTION
GND
Ground
TCK
Test clock. One of four pins required by IEEE Std 1149.1-1990. Test operations of the device are synchronous to the test
clock. Data is captured on the rising edge of TCK and outputs change on the falling edge of TCK.
TDI
Test data input. One of four pins required by IEEE Std 1149.1-1990. TDI is the serial input for shifting data through the
instruction register (IR) or selected data register (DR). An internal pullup forces TDI to a high level if left unconnected.
TDO
Test data output. One of four pins required by IEEE Std 1149.1-1990. TDO is the serial output for shifting data through
the IR or selected DR.
TMS
Test mode select. One of four pins required by IEEE Std 1149.1-1990. The TMS input directs the device through its TAP
controller states. An internal pullup forces TMS to a high level if left unconnected.
