Data Sheet

Zarlink Semiconductor Inc.
Test Mode Selection Inputs (TMS)
- The TAP Controller uses the logic signals received at the TMS input to
control test operations. The TMS signals are sampled at the rising edge of the TCK pulse. This pin is
internally pulled to high when it is not driven from an external source.
Test Data Input (TDi)
- Serial input data applied to this port is fed either into the instruction register or into a
test data register, depending on the sequence previously applied to the TMS input. The registers are
described in a subsequent section. The received input data is sampled at the rising edge of the TCK pulse.
This pin is internally pulled to high when it is not driven from an external source.
Test Data Output (TDo)
- Depending on the sequence previously applied to the TMS input, the contents of
either the instruction register or test data register are serially shifted out towards TDo. The data from 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)
- Resets the JTAG scan structure. This pin is internally pulled to high when it is not
driven from an external source.
21.2 Instruction Register
The ZL50022 uses the public instructions defined in the IEEE-1149.1 standard. The JTAG interface contains a
four-bit instruction register. Instructions are serially loaded into the instruction register from the TDi when the TAP
Controller is in its shifted-OR state. These instructions are subsequently decoded to achieve two basic functions: to
select the test data register that may operate while the instruction is current and to define the serial test data
register path that is used to shift data between TDi and TDo during data register scanning.
21.3 Test Data Registers
As specified in the IEEE-1149.1 standard, the ZL50022 JTAG interface contains three test data registers:
The 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 ZL50022 core logic.
The Bypass Register
- The Bypass register is a single stage shift register that provides a one-bit path from
TDi to TDo.
The Device Identification Register
- The JTAG device ID for the ZL50022 is 0C36614B

21.4 BSDL
A Boundary Scan Description Language (BSDL) file is available from Zarlink Semiconductor to aid in the use of the
IEEE-1149.1 test interface.
