3.4.4
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 SSP, I
section in this data sheet.
3.4.4.1
Figure 3-9 shows the diagram for this pin. This pin is
configurable to function as one of the following:
• a general purpose I/O
• an analog input for the ADC
• an external edge triggered interrupt
3.4.4.2
Figure 3-9 shows the diagram for this pin. This pin is
configurable to function as one of the following:
• a general purpose I/O
• an analog input for the ADC
• a PWM output
• an analog input to Comparator C1 or C2
3.4.4.3
Figure 3-9 shows the diagram for this pin. This pin is
configurable to function as one of the following:
• a general purpose I/O
• an analog input for the ADC
• a PWM output
3.4.4.4
