Apply 3.0 to 5.5V to the VCC1 and VCC2 pins and 0V to the
VSS pin. The VCC apply condition is that VCC2 = VCC1
(1)
.
Applies the power supply for the A/D converter. Connect the
AVCC pin to VCC1. Connect the AVSS pin to VSS.
The microcomputer is in a reset state when applying “L” to the
this pin.
Connect this pin to VSS.
Connect this pin to VSS.
I/O pins for the main clock oscillation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT
(2)
.
To use the external clock, input the clock from XIN and leave
XOUT open.
I/O pins for a sub clock oscillation circuit. Connect a crystal
oscillator between XCIN and XCOUT
(2)
.
To use the external clock, input the clock from XCIN and leave
XCOUT open.
The clock of the same cycle as fC, f8, or f32 is output.
