DEVICE IDENTIFICATION
The device identification (ID) is based on the manufacturer identity, part-number and version codes described
in IEEE standard 1149.1 on Boundary Scan, using the manufacturer code assigned by the Joint Electron
Device Engineering Council (JEDEC). The serial format for this ID is shown below:
MSB
Version
LSB
Part-Number
0000 1101 0111 1100
Manufacturer Identity
000 0110 1011

The device identification is not currently provided as a boundary scan message. However, the manufacturer
identity and part-number are implemented with read-only capability for microprocessor read access. The man-
ufacturer identity for TranSwitch devices is 107 (06B hex.). The part-number of the L3M device is 03452 (0D7C
hex.). In addition, the read-only segment is expanded to include a 4-bit mask level field and a 4-bit future
growth field, as shown below:
