12.2 JTAG Test Port
The 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 and on the boundary scan cells, refer to the Operations
