Boot ROM IDs
2-byte device ID as follows:
Bit 15 is 0 if the part is ROM or ROMless, 1 if the part is
EPROM.
Bit 14 is a 0 if unsecured.
Bit 13–bit 9 are lower five bits of first ASCII letter.
Bit 8–bit 4 are lower five bits of second ASCII letter.
Bit 3–bit 0 are last digit of part number.
Alternatively:
If bit 8 – bit 6 are %111, then bit 5–bit 0 are last digit
of number part.
Table 5 gives guidance on where to find the ID for many M68HC11
devices.
