1.5.2 Oscillator Pins (OSC1 and OSC2)
The OSC1 and OSC2 pins are the connections to an external clock
source or crystal/ceramic resonator.
1.5.3 External Reset (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.
The RST pin contains an internal pullup resistor.
For additional information, see Section 6. System Integration Module
(SIM).
1.5.4 External Interrupt Pin (IRQ1)
IRQ1 is an asynchronous external interrupt pin.
The IRQ1 pin contains an internal pullup resistor.
