Section 8 I/O Ports
8.5
Port B is an input-only port also functioning as an interrupt input pin, analog input pin, and
comparator pin. Figure 8.5 shows its pin configuration.
Port B has the following registers.
• Port data register B (PDRB)
• Port mode register B (PMRB)
8.5.1
PDRB is a register that stores data of port B.

Description
Reserved
The read value is undefined. These bits cannot be
modified.
Reading PDRB always gives the pin states. However, if
a port B pin is selected as an analog input channel by
the CH3 to CH0 bits in AMR of the A/D converter, that
pin is read as 0 regardless of the input voltage.
