MEMORY MAP
There are four memory map segments. One, with leading address digit 0, contains registers used for global
(common) operation, including device identification (ID). The other three segments have addresses with lead-
ing digit X, and their registers correspond to the mapper channel identified by X (where X = 1, 2, 3).
Register status types are: R/W: Read/write; R: Read only; R(L)/W: Read(Latched)/Write.
Read only registers must not be written. Registers that are shown with all bits Reserved must not be
accessed, unless otherwise indicated. When writing to a register that contains from one to seven bits
that are shown as Reserved or Not Used, these bits should be written as zeros, unless otherwise indi-
cated. Please note that Reserved bits may perform specific test functions and must be set to the spec-
ified value when written in order to assure proper device operation, while Not Used bits have no function
but should to be set to the specified value when written in case they are assigned functions in future ver-
sions of the device, for purposes of backwards compatibility with existing application designs.
Please note that a hardware reset (lead RESET), or a software reset via control bit RESETS (bit 0 in register
0C7H), will result in all per channel control bits, Reserved and Not Used bits in used registers (1CXH-3CXH,
where X = any listed value in the memory map) being reset to the 1 state, and all common control bits,
Reserved and Not Used bits in used registers (0CXH) being reset to the 0 state.
DEVICE IDENTIFICATION REGISTERS (Manufacturer ID plus Triple Level 3 Mapper ID))
Description
The manufacturer and device identifiers are based on the manufacturer ID format given in IEEE standard
1149.1 on Boundary Scan, the ID number assigned by the Solid State Products Engineering Council (JEDEC)
to The TranSwitch Corporation, and the part number digits assigned to the TL3M device by TranSwitch. The
serial format for this 4-byte ID is shown below, where the MSB is bit 7 in register 0F3H and the LSB (fixed at
the value of 1) is bit 0 in register 0F0H:
The manufacturer ID for all TranSwitch devices is defined as the binary equivalent of 107, located in bits 3
through 0 in register 0F1H, and bits 7 through 1 of register 0F0H. The part number of the TL3M is 03453, which
is expressed as a binary number in bits 3 through 0 in register 0F3H, bits 7 through 0 in register 0F2H, and bits
7 through 4 in register 0F1H. The revision field is in bits 7 through 4 of register 0F3H.
