NSE-8G™ Standard Product Data Sheet  
Preliminary  
10 Normal Mode Register Description  
Normal mode registers are used to configure and monitor the operation of the NSE. Normal mode  
registers (as opposed to test mode registers) are selected when A[11] is set low.  
Notes on Normal Mode Register Bits:  
1. Writing values into unused register bits has no effect. However, to ensure software  
compatibility with future, feature-enhanced versions of this product, unused register bits must  
be written with logic 0. Reading back unused bits can produce either a logic one or a logic 0;  
hence, unused register bits should be masked off by software when read.  
2. All configuration bits that can be written into can also be read back. This allows the processor  
controlling the TSB to determine the programming state of the block.  
3. Writeable normal mode register bits are cleared to logic 0 upon reset unless otherwise noted.  
4. Writing into read-only normal mode register bit locations does not affect NSE-8G operation  
unless otherwise noted.  
5. For registers above 100H, only a one port set of the 12 ports are shown. The Register  
addresses are shown for example as: 0100H + N*20H, N here is the port number between 0  
and 11. This is done to prevent unnecessary duplication of otherwise identical register sets.
