10 Normal Mode Register Description
Normal mode registers are used to configure and monitor the operation of the TSE. Normal
mode registers (as opposed to test mode registers) are selected when TRS (A[12]) is low.
Notes on Normal Mode Register Bits:
1. Unused bits have no effect. However, to ensure software compatibility with future, feature-enhanced
versions of the product, unused register bits must be written with logic zero. Reading back unused bits can
produce either a logic one or a logic zero; hence unused register bits should be masked off by software
when read.
2. Writeable normal mode register bits are cleared to logic zero upon reset unless otherwise noted.
3. Writing into read-only normal mode register bit locations does not affect TSE operation unless otherwise
noted.
4. Certain register bits are reserved. These bits are associated with megacell functions that are unused in this
application. To ensure that the TSE operates as intended, reserved register bits must only be written with
the logic level as specified. Writing to reserved registers should be avoided.
