General Description
1.6.2 Oscillator Pins (OSC1 and OSC2)
1.6.3 External Reset Pin (RST)
1.6.4 External Interrupt Pin (IRQ)
Technical Data
40
Use a high-frequency-response ceramic capacitor for C1. C2 is an
optional bulk current bypass capacitor for use in applications that require
the port pins to source high current levels.
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit.
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. This pin contains an internal pullup
resistor.
IRQ is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor.
