I VCC1
I VCC1
O VCC1
Input pin to switch processor mode. Connect the CNVSS pin
to VSS via a resistor to start up after a reset in single-chip
mode.
I/O pins for the main clock oscillator. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT ⁽¹⁾. To
apply an external clock, connect it to XIN and leave XOUT
open.
Sub clock input XCIN
Sub clock output XCOUT
I VCC1
O VCC1
I/O pins for a sub clock oscillator. Connect a crystal oscillator
between XCIN and XCOUT ⁽¹⁾.
To apply an external clock, connect it to XCIN and leave
XCOUT open.
