JTAG Test Port
The S/UNI-MACH48 JTAG Test Access Port (TAP) allows access to the TAP controller and the 4
TAP registers: instruction, bypass, device identification and boundary scan. Using the TAP,
device input logic levels can be read, device outputs can be forced, the device can be identified
and the device scan path can be bypassed. For more details on the JTAG port, please refer to the
Operations section.
