CHAPTER 24 MASK OPTIONS
Mask ROM versions are provided with the following mask options.
1.
Power-on-clear (POC) circuit
•
POC cannot be used
•
POC used (detection voltage: V
POC
= 2.85 V
±
0.15 V)
•
POC used (detection voltage: V
POC
= 3.5 V
±
0.2 V)
2.
Ring-OSC
•
Cannot be stopped
•
Can be stopped by software
3.
Pull-up resistor of P60 to P63 pins
•
Pull-up resistor can be incorporated in 1-bit units
(Pull-up resistors are not available for the flash memory versions.)
Flash memory versions that support the mask options of the mask ROM versions are as follows.
