Figure 6. Port B Pin Structure
10.3.2 Port B (PB0-PB7) in 16-bit Multiplexed Address/Data Mode
In this mode, Port B becomes the low-order data bus byte to the MCU chip. When reading
an internal high-order location, data is presented on Port B pins to the MCU. When writing
to an internal high-order location, data present on Port B pins from the MCU is written to the
desired location.
