General Description
1.5.2 Oscillator Pins (OSC1 and OSC2)
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit. (See Section 8. Clock Generator Module (CGM).)
1.5.3 External Reset Pin (RST)
A logic 0 on the RST pin forces the MCU to a known startup state. RST
is bidirectional, allowing a reset of the entire system. It is driven low when
any internal reset source is asserted. (See Section 9. System
Integration Module (SIM) for more information.)
1.5.4 External Interrupt Pin (IRQ)
IRQ is an asynchronous external interrupt pin. (See Section 14.
External Interrupt (IRQ).)
1.5.5 Analog Power Supply Pin (V_DDA/V_DDAREF)
V_DDA/V_DDAREF is the power supply pin for the analog portion of the chip.
These modules are the analog-to-digital converter (ADC) and the clock
generator module (CGM). (See Section 8. Clock Generator Module
(CGM) and Section 19. Analog-to-Digital Converter (ADC).)
1.5.6 ADC High Reference Pin (V_REFH)
V_REFH is the high reference voltage for all analog-to-digital conversions.
(See Section 19. Analog-to-Digital Converter (ADC).)
