Apply 4.2 to 5.5 V to both VCC pins.
Apply 0 V to the VSS pin
Supplies power to the A/D converter. Connect the AVCC pin to VCC and the
AVSS pin to VSS
___________
The microcomputer is in a reset state when "L" is applied to the RESET pin
Switches processor mode. Connect the CNVSS pin to VSS
Connect the BYTE pin to VSS
I/O pins for the main clock oscillation circuit. Connect a ceramic resonator
or crystal oscillator between XIN and XOUT. To apply external clock, apply it
to XIN and leave XOUT open.
I/O pins for the sub clock oscillation circuit. Connect a crystal oscillator
between XCIN and XCOUT. To apply external clock, apply it to XCIN and
leave XCOUT open
Outputs the clock having the same frequency as fC, f8 or f32
