10.6.4 IEEE 1149.1 JTAG Boundary Scan
IEEE 1149.1 JTAG Boundary Scan allows pin-level access independent of the device packaging technology.
IEEE 1149.1 JTAG Boundary Scan is enabled when JTAGSEL is high. The SAMPLE, EXTEST and BYPASS functions
are implemented. In ICE debug mode, the ARM processor responds with a non-JTAG chip ID that identifies the
processor to the ICE system. This is not IEEE 1149.1 JTAG-compliant.
It is not possible to switch directly between JTAG and ICE operations. A chip reset must be performed after JTAGSEL is
changed.
A Boundary-scan Descriptor Language (BSDL) file is provided to set up test.
