area

Function set ROM

Function set ROM is assigned to address FFD816 to FFDA16.

Valid/invaid of low voltage detection circuit can be selected.

Oscillation mode can be selected.

Enable/disable of watchdog timer and STP instruction can be selected.

ROM code protect

ROM code protect is assigned to address FFDB16.

Read/write the built-in QzROM by serial programmer is disabled by setting “00”

to ROM code protect.
