Modes of Operation and Pin Descriptions
7-pin
Ceramic
resonator
A ceramic resonator may be used instead of a crystal in cost sensitive
applications. The circuit shown in Figure 5(a) is recommended when
using either a crystal or a ceramic resonator. Figure 5(e) lists the
recommended capacitance and feedback resistance values. The
manufacturer of the particular ceramic resonator being considered
should be consulted for specific information.
External clock
An external clock should be applied to the OSC1 input, with the OSC2
(see Table 23) does not apply when using an external clock input. The
equivalent specification of the external clock source should be used in
lieu of tOCOV.
LVI
This active low input pin is used to indicate a drop in supply voltage
below a useful operating level. Driving this pin low initiates either a
pre-defined software routine or a hardware interrupt (see Low voltage
indicator interrupt). The LVI pin contains an internal Schmitt trigger to
improve noise immunity.
RESET
This active low input-only pin is used to reset the MCU. Applying a logic
zero to this pin forces the device to a known start-up state. The RESET
pin has an internal Schmitt trigger to improve noise immunity.
PA0PA7
These eight I/O lines comprise port A. The state of any pin is software
programmable, and all the pins are configured as inputs with fixed
pull-up resistors during power-on or reset.
PB0PB7
These eight pins comprise port B. The state of any pin is software
programmable, and all the pins are configured as inputs with fixed
pull-down resistors during power-on or reset.
NOTE:
PB5–PB7 are not bonded out in the 28-pin package.
