NORMAL MODE REGISTER DESCRIPTION
Normal mode registers are used to configure and monitor the operation of the
TECT3. Normal mode registers (as opposed to test mode registers) are selected
when TRS (A[13]) is low.
Notes on Normal Mode Register Bits:
1) Writing values into unused register bits typically has no effect. However, to
ensure software compatibility with future, feature-enhanced versions of the
product, unused register bit 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.
2) All configuration bits that can be written into can also be read back. This
allows the processor controlling the TECT3 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
TECT3 operation unless otherwise noted.
The register descriptions are contained in a separate TECT3 register description
document.
