22.1.1.3 Device ID Register (DID)
Accessing the DID register provides key attributes to the development tool concerning the
MCU. This information is also transmitted via the auxiliary output port upon exit of READI
reset (RSTI), if EVTI is asserted at RSTI negation. Table 22-6 gives the bit descriptions.
