area
Function set ROM
Function set ROM is assigned to address FFD816 to FFDA16.
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.
