7.2
In accordance with the IEEE 1149.1 standard, the ZL50232 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.
7.3
As specified in IEEE 1149.1, the ZL50232 JTAG Interface contains three test data registers:

Test Reset (TRST)
This pin is used to reset the JTAG scan structure. This pin is internally pulled to V
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 ZL50232 core logic.
Bypass Register
The Bypass register is a single stage shift register that provides a one-bit path from TDI to TDO.
Device Identification register
The Device Identification register provides access to the following encoded information:
device version number, part number and manufacturer's name.
