3.3.2 Enabling System Area

In order to enable parameters in the system area, CFEN and BCC (see the Administrator's Manual) of the

system area must be set to valid values. If CFEN and BCC are not set to valid values, default values defined

by each parameter will be applied.

Table 3-19 lists the setting application timings after rewriting parameters in the system area while CFEN and

BCC are enabled. New parameter setting is applied to RORF, ROSI, and SECURITY immediately after

rewriting, and applied to other parameters after turning power supply ON from OFF,or applied to other

parameters after the self-reset by the WREG command of the serial communication.

Table 3-19 Parameter Application Timing

is applied after rewriting parameters

when CFEN is enabled.
