Parity / Write Protection
Write Protection
• Flash Memory
• Serial Interface
• Parity: Internal reset when parity error
generated on Read or Write
• Write Protection :

Illegal memory access detection
Clock
Stop Detection / Frequency check
• Illegal memory access:
• Stop detection :
generates “internal reset”
possible to detect by WWDT
• Trap instruction:
• Frequency check:
“FF” instruction generates “internal reset”
possible to check by Timer function

ADC
Multiple Input signal selectable
ADC measurement sources:
• External ADC input pins
• External / Internal AVref sources
• Internal Vref (1.4V typ)
• Temperature sensor
