*1 Depends on program. (Values in the above table are applied in the case where the software

duty is about 5%.)

*2 PORT0 = P0.0 to P0.3, PORT1 = P1.0 to P1.3, PORT2 = P2.0 to P2.3, PORT3 = P3.0 to P3.3,

PORT4 = P4.0 to P4.3, PORT5 = P5.0 to P5.3, PORT6 = P6.0 to P6.3, PORT7 = P7.0 to P7.3

Note: The input of the constant voltage circuit is directly connected to the power supply (VSS2).
