NORMAL MODE REGISTER DESCRIPTION

Normal mode registers are used to configure and monitor the operation of the

TEMAP-84. Normal mode registers (as opposed to test mode registers) are

selected when TRS (A[12]) is low.

The register descriptions are contained in a separate TEMAP-84 register

description document.

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 TEMAP-84 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

TEMAP-84 operation unless otherwise noted.
