MANUFACTURER AND DEVICE IDENTIFICATION DESCRIPTION
The manufacturer and device identification are based on the field format given in IEEE standard 1149.1 on
Boundary Scan, and the ID assigned by the Solid State Products Engineering Council (JEDEC) to the
TranSwitch Corporation. The serial format for this ID, which is located in registers 000H through 003H, is
shown below. Bit 7 in register 003H is at the left and bit 0 of register 000H is at the right:
The manufacturer ID assigned for TranSwitch devices is defined as 107 Decimal, located in bits 7 through 1
(LSB) of register 000H, and bits 3 (MSB) through 0 of register 001H. The part number of the TEMx28 is 04222,
which is expressed as a binary number in bits 7 through 4 (LSB) in register 001H, bits 7 through 0 in 002H, and
bits 3 (MSB) through 0 in 003H. The revision field occupies bits 7 through 4 (LSB) in register 003H. The regis-
ters at address 004H is a read/write locations that is reserved for future use.

Not used:
Reset Device: This bit is equivalent to the hardware reset. When a 1 is
written to this bit, the internal FIFOs and logic are reset to preset values,
counters and control bits in the memory map are reset to zero. This bit is
self clearing. Four microseconds after this bit is written with a 1, status
bit RESETD (bit 0, register 059H) transitions to a 1. This transition indi-
cates that the reset operation is complete and microprocessor access of
the device can begin.
Not used:
Test Analyzer Add/Drop Direction: When a 0 is written into this bit, the
PRBS test analyzer for all channels are configured to be in the receive
direction. Writing a 1 to this bit configures the PRBS analyzers to be in
the transmit direction.
Not used:
Test Generator Add/Drop Direction: When a 0 is written into this bit,
the PRBS test generators for all channels are configured to be in the
transmit direction. Writing a 1 to this bit configures the PRBS generators
to be in the receive direction.
