17.2
The ZL50016 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.
17.3
As specified in the IEEE-1149.1 standard, the ZL50016 JTAG interface contains three test data registers:

•
17.4
A Boundary Scan Description Language (BSDL) file is available from Zarlink Semiconductor to aid in the use of the
IEEE-1149.1 test interface.
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 ZL50016 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 ZL50016 is 0C36014B
