General Description
MOTOROLA
1.5.1 VDD and VSS
Power is supplied to the microcontroller using these two pins. VDD is the
positive supply and VSS is ground.
1.5.2 IRQ
This pin has a mask selectable option that provides two different choices
of interrupt triggering sensitivity. The IRQ pin contains an internal
Schmitt trigger as part of its input to improve noise immunity. Refer to
Section 4. Interrupts for more detail.
1.5.3 OSC1 and OSC2
These pins provide control input for an on-chip clock oscillator circuit. A
crystal, a ceramic resonator, a resistor/capacitor combination, or an
external signal connects to these pins providing a system clock. The
internal bus rate is one-half the external oscillator frequency.
1.5.4 RESET
This active low pin is used to reset the MCU to a known startup state by
pulling RESET low. The RESET pin contains an internal Schmitt trigger
as part of its input to improve noise immunity.
1.5.5 TCAP
This pin controls the input capture feature for the on-chip programmable
timer. The TCAP pin contains an internal Schmitt trigger as part of its
input to improve noise immunity.
1.5.6 TCMP
The TCMP pin provides an output for the output compare feature of the
on-chip timer subsystem.
