Description
Reference voltage output, normally VDD/2
X1 and X2 are connected to an external 32768Hz crystal or resonator for
the system clock.
External low pass filter pin used for the frequency up conversion circuit.
Schmitt trigger reset input. Active low.
Positive power supply
Negative power supply, ground.
DTMF receiver positive power supply
DTMF receiver negative power supply
Note: Each pin on PA can be programmed through a configuration option to have a wake-up function.
