Description
Apply the flash memory program and erase voltage to the
VCC1 pin, and VCC2 to the VCC2 pin. The VCC application
condition is that VCC2 ≤ VCC1. Apply 0 V to the VSS pin.
Connect to the VCC1 pin.
Reset input pin.
Input a high-level signal to the XIN pin and open the XOUT pin
when the main clock is not used.
Connect a ceramic resonator or crystal between pins XIN and
XOUT when the main clock is used. To input an externally
generated clock, input it to the XIN pin and open the XOUT pin.
Connect this pin to VSS or VCC1.
Connect the AVCC pin to VCC1 and the AVSS pin to VSS,
respectively.
Reference voltage input pin for A/D converter. When using
standard serial I/O mode 1, and power supply to VREF is not
supplied, connect with VSS.
Input a high- or low-level signal or leave open.
