Function
Data output pins
Data input pins
Clock input/output pins.
SCK1 outputs NMOS push-pull.
I²C clock input/output pins.
These pins drive bus. The output of SCL0 is
NMOS open drain.
I²C data input/output pins.
These pins drive bus. The output of SDA0 is
NMOS open drain.
Analog input pins
Pin for input of an external trigger to start A/D
conversion
Analog output pins for the D/A converter^*1.
Power supply pin for the A/D converter, D/A
converter^*1 and DTMF generation circuit^*1. If
none of the A/D converter, D/A converter^*1 and
DTMF generation circuit^*1 is used, connect this
pin to the system power supply (+5 V).
Ground pin for the A/D converter, D/A
converter^*1, and DTMF generator^*1. Connect this
pin to the system power supply (0 V).
Reference voltage input pin for the A/D converter
and D/A converter^*1. If neither the A/D converter
nor D/A converter^*1 is used, connect this pin to
the system power supply (+5 V).
