NSE-8G™ Standard Product Data Sheet  
Preliminary  
PMCTST  
The PMCTST bit is used to configure the NSE-8G for PMC's manufacturing tests. When  
PMCTST is set to logic one, the NSE-8G microprocessor port becomes the test access port  
used to run the PMC "canned" manufacturing test vectors. As well, the analog blocks are  
placed in IDDQ mode = the digital circuitry within the analog blocks is held static The  
PMCTST can be cleared by setting CSB to logic one or by writing logic zero to the bit.  
PMCATST  
The PMCATST bit is used to configure the analog portion of the NSE-8G for PMC's  
manufacturing tests. The PMCATST bit can be cleared by setting both CSB to logic one and  
RSTB to logic zero. PMCATST can also be cleared by writing logic zero to the bit.  
11.2 JTAG Test Port  
The NSE JTAG Test Access Port (TAP) allows access to the TAP controller and the four 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.
