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:
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.
allows the processor controlling the TEMAP-84 to determine the
programming state of the block.
