Port B
Description
The input value of each pin is read by reading this
register.
However, if a port B pin is designated as an analog input
channel by ADCSR in the A/D converter or as an external
comparison voltage input pin by LVDCR in the low-
voltage detection circuit, the corresponding bit is read
as 0.
