General Description
1.5.3 Oscillator Pins (OSC1 and OSC2)
1.5.4 External Reset Pin (RST)
1.5.5 External Interrupt Pin (IRQ1/V
1.5.6 USB Data Pins (DPLUS0–DPLUS4 and DMINUS0–DMINUS4)
1.5.7 Voltage Regulator Out (REGOUT)
Advance Information
30
The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit.
A logic zero 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. The RST pin contains an
internal pullup device.
(SIM).)
IRQ1/V
the OTPROM programming power pin. The IRQ1/V
internal pullup device.
DPLUS0–DPLUS4 and DMINUS0–DMINUS4 are the differential data
lines used by the USB module.
Module
REGOUT is the 3.3V output of the on-chip voltage regulator. It is used
to supply the voltage for the external pullup resistor required by the USB
on either DPLUS or DMINUS lines, depending on type of USB function.
REGOUT is also used internally for the USB data driver and the Phase-
locked Loop circuit. The REGOUT pin requires an external bulk
capacitor 1 F or larger and a bypass capacitor.
