1.7 Functional Pin Description
The following paragraphs give a description of the general function of
each pin.
1.7.1 VDD and VSS
Power is supplied to the MCU through VDD and VSS. VDD is the positive
supply and VSS is ground. The MCU operates from a single power
supply.
Rapid signal transitions occur on the MCU pins. The short rise and fall
times place very high short-duration current demands on the power
supply. To prevent noise problems, special care should be taken to
provide good power supply bypassing at the MCU by using bypass
capacitors with high-frequency characteristics that are positioned as
close to the MCU as possible.
1.7.2 OSC1 and OSC2
The OSC1 and OSC2 pins are the connections for the 2-pin on-chip
oscillator. The OSC1 and OSC2 pins also can be used in conjunction
with the PB1/OSC3 pin to create a more stable 3-pin RC oscillator. The
OSC1, OSC2, and PB1/OSC3 pins can accept these sets of
components:
1. A crystal, as shown in Figure 1-3(a)
2. A ceramic resonator, as shown in Figure 1-3(a)
3. An external resistor and capacitor using two pins, as shown in
4. An external resistor and capacitor using three pins, as shown in
5. An external clock signal, as shown in Figure 1-3(d)
The frequency, fosc, of the oscillator or external clock source is divided
by two to produce the internal operating frequency fop. The oscillator
type is selected by two mask option register bits.
