If the EXM pin is high and the INT1 is low upon reset, the mwait register is initialized to all 1s (15 wait-states for all
external memory). Otherwise, the mwait register is initialized to all 0s (0 wait-states) upon reset.

Users ROMCODE ID:
The ROMCODE ID is the 9-bit binary value of the following expression:
(20 x value for first letter) + (value of second letter), where the values of the letters are
in the following table. For example, ROMCODE GK is
(20 x 6) + (9) = 129 or 0 1000 0001.
DSP1627x36 with 36K IROM and no EROM in MAP1 or MAP3.
