2.3.3 Configuration Registers.

The ST52T410/ST52x420 configuration Registers

allow the configuration of all the blocks of the fuzzy

microcontroller. Table 2.3 describes the functions

and the related peripherals of each of the

Configuration

Registers.

using

the

load

instructions, the Configuration Registers can be

set by using values stored in the Program Memory

(EPROM) or in RAM.

Use and meaning of each register will be described

in further details in the corresponding section.
