2.1.1.1. JTAG Pins

Table 2.  JTAG Pin
Pin Function Description
TDI Serial input pin for:
  • instructions
  • boundary-scan test (BST) data
  • programming data
  • TDI is sampled on the rising edge of TCK
  • TDI pins have internal weak pull-up resistors.
TDO Serial output pin for:
  • instructions
  • boundary-scan test data
  • programming data
  • TDO is sampled on the falling edge of TCK
  • The pin is tri-stated if data is not shifted out of the device.
TMS Input pin that provides the control signal to determine the transitions of the TAP controller state machine.
  • TMS is sampled on the rising edge of TCK
  • TMS pins have internal weak pull-up resistors.
TCK Clock input to the BST circuitry.

All the JTAG pins are powered by the VCCIO 1B. In JTAG mode, the I/O pins support the LVTTL/LVCMOS 3.3-1.5V standards.
