Name and Functions
Power supply: All VCC pins should be connected to
the system power supply (+5 V)
Ground: All VSS pins should be connected to the
system power supply (0 V)
Connected a 0.1 µF stabilization capacitor between
the CVCC pin and ground.
DTMF generator reference level: This is a power
supply pin for the reference level for DTMF.
System clock: These pins connect to a crystal or
ceramic oscillator, or can be used to input external
an clock. See section 4, Clock Pulse Generators, for
a typical connection diagram.

Subclock: These pins connect to a 32.768-kHz
crystal oscillator. See section 4, Clock Pulse
Generators, for a typical connection diagram.
Reset: When this pin is driven low, the chip is reset
Test: This is a test pin, not for use in applica-tion
systems. It should be connected to VSS.
External interrupt request 0 to 4: These are input
pins for external interrupts for which there is a choice
between rising and falling edge sensing
Input
Wakeup interrupt request 0 to 7: These are input
pins for external interrupts that are detected at the
falling edge
