PIN DESCRIPTIONS AND

DIAGRAMS

Each PORTB pin is multiplexed with other functions. The

pins and their combined functions are briefly described

here. For specific information about individual functions

such as the LCD or interrupts, refer to the appropriate

section in this data sheet.

3.4.3.1 RB0/INT/SEG0

Figure 3-9 shows the diagram for this pin. The RB0 pin

is configurable to function as one of the following:

• a general purpose I/O

• an external edge triggered interrupt

• an analog output for the LCD

3.4.3.2 RB1/SEG1

Figure 3-9 shows the diagram for this pin. The RB1 pin

is configurable to function as one of the following:

• a general purpose I/O

• an analog output for the LCD

3.4.3.3 RB2/SEG2

Figure 3-9 shows the diagram for this pin. The RB2 pin

is configurable to function as one of the following:

• a general purpose I/O

• an analog output for the LCD

3.4.3.4 RB3/SEG3

Figure 3-9 shows the diagram for this pin. The RB3 pin

is configurable to function as one of the following:

• a general purpose I/O

• an analog output for the LCD
