Notes: 1. In order to eliminate power supply noise, a 0.1 µF or greater capacitor should be connected externally across power supply pins VDD and VSS. In addition, a 0.1 µF or greater capacitor should also be connected across VDD and CNVSS. (The recommended crystal oscillator is Murata model no. CSA8.00MTZ (8.00 MHz), shown in the measurement circuit diagram.) 2. Pin names for the different quantities are given as follows. (1) Dedicated pins: Dedicated pin name (2) Double/triple-function ports *When standards are the same: I/O port name *When standard of functions other than the I/O port are different: function pin name 3. The sum of currents flowing from the IC should not exceed 20 mA. 4. The sum of currents flowing into the IC (IOL1+IOL2) should not exceed 30 mA. 5. The sum of the average currents of ports P24 to P27 flowing into the IC should not exceed 20 mA. 6. When using a CPU oscillation circuit (XIN, XOUT), a crystal oscillator or a ceramic resonator should be used.
