Data Sheet
19
Zarlink Semiconductor Inc.
Test Data Output (TDO)
Depending on the sequence previously applied to the TMS input, the contents of either the instruction
register or data register are serially shifted out towards the TDO. The data from the TDO is clocked on the
falling edge of the TCK pulses. When no data is shifted through the Boundary Scan cells, the TDO driver is
set to a high impedance state.
Test Reset (TRST)
This pin is used to reset the JTAG scan structure. This pin is internally pulled to V
SS
.
Instruction Register
In accordance with the IEEE 1149.1 standard, the MT93L00 uses public instructions. The JTAG Interface contains
a 3-bit instruction register. Instructions are serially loaded into the instruction register from the TDI when the TAP
Controller is in its shifted-IR state. Subsequently, the instructions are decoded to achieve two basic functions: to
select the test data register that will operate while the instruction is current, and to define the serial test data register
path, which is used to shift data between TDI and TDO during data register scanning.
Test Data Registers
As specified in IEEE 1149.1, the MT93L00 JTAG Interface contains three test data registers:
Boundary-Scan register
The Boundary-Scan register consists of a series of Boundary-Scan cells arranged to form a scan path
around the boundary of the MT93L00 core logic.
Bypass Register
The Bypass register is a single stage shift register that provides a one-bit path from TDI TDO.
Device Identification register
The Device Identification register provides access to the following encoded information:
device version number, part number and manufacturer's name.
