NORMAL MODE REGISTER DESCRIPTION
Normal mode registers are used to configure and monitor the operation of the
TUPP . Normal mode registers (as opposed to test mode registers) are selected
when A[7] is low.
Notes on Normal Mode Register Bits:
1. Writing values into unused register bits has no effect. However, to ensure
2. All configuration bits that can be written into can also be read back. This
3. Writable normal mode register bits are cleared to logic 0 upon reset unless
4. Writing into read-only normal mode register bit locations does not affect

software compatibility with future, feature-enhanced versions of the product,
unused register bits must be written with logic 0. Reading back unused bits
can produce either a logic 1 or a logic 0; hence unused register bits should be
masked off by software when read.
