Power supply
TRST_
Test mode reset
TRST_ operates the JTAG standard. Consult the JTAG
specifications for use in boundary-scan testing. These signals meet
the requirements of the Raven and Jeeni debuggers.
TCK
Test mode clock
TCK operates the JTAG standard. Consult the JTAG specifications
for use in boundary-scan testing. These signals meet the
requirements of the Raven and Jeeni debuggers.
