1.6.2 Oscillator Pins (OSC1 and OSC2)
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
1.6.3 External Reset Pin (RST)
A logic 0 on the RST pin forces the MCU to a known start-up state. RST
is bidirectional, allowing a reset of the entire system. It is driven low when
any internal reset source is asserted. This pin contains an internal pullup
1.6.4 External Interrupt Pin (IRQ)
IRQ is an asynchronous external interrupt pin. This pin contains an
1.6.5 Analog Power Supply Pin (VDDA)
VDDA is the power supply pin for the clock generator module (CGM).
1.6.6 Analog Ground Pin (VSSA)
The VSSA analog ground pin is used only for the ground connections for
the clock generator module (CGM) section of the circuit and should be
decoupled as per the V
SS digital ground pin. See Section 9. Clock
1.6.7 Analog Ground Pin (AVSS/VREFL)
The AVSS analog ground pin is used only for the ground connections for
the analog to digital convertor (ADC) and should be decoupled as per the
VSS digital ground pin.
