the outputs of the block and consequently the device outputs (refer to the  
"Test Mode 0 Details" in the "Test Features" section).  
HIZIO:  
The HIZIO bit controls the tri-state modes of the output pins of the TECT3.  
While the HIZIO bit is a logic 1, all output pins of the TECT3, except the data  
bus, are held in a high-impedance state. The microprocessor interface is still  
active.  
HIZDATA:  
The HIZDATA bit controls the tri-state modes of the TECT3. While the HIZIO  
bit is a logic 1, all output pins of the TECT3, except the data bus, are held in a  
high-impedance state. While the HIZDATA bit is a logic 1, the data bus is also  
held in a high-impedance state which inhibits microprocessor read cycles.  
11.1 JTAG Test Port  
The TECT3 JTAG Test Access Port (TAP) allows access to the TAP controller  
and the 4 TAP registers: instruction, bypass, device identification and boundary  
scan. Using the TAP, device input logic levels can be read, device outputs can  
be forced, the device can be identified and the device scan path can be  
bypassed. For more details on the JTAG port, please refer to the Operations  
section.
