8.3
The port 4 is a 4-bit input port also functioning as A/D converter analog input pins. The port 4 of
the H8S/2218 Group has the same function as that of the H8S/2212 Group. The port 4 has the
following register.
• Port 4 register (PORT4)
8.3.1
PORT4 indicates the pin states of the port 4.
Note: * Determined by the states of pins P43 to P40.
8.3.2
The port 4 also functions as A/D converter analog input (AN3 to AN0) pins.
