3.19.1 JTAG ID Register
This is a read-only register located inside the JTAG module, and is used to recognize the
device(s) connected to the JTAG interface. Its content is shifted out when
INSTRUCTION register contains the IDCODE command (opcode 04_H), and the same is
also true immediately after reset.
The JTAG ID register contents for the XC886/888 Flash devices are given in Table 34.
