Valid/invalid 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.
