I
Function
I/O pins for the main clock oscillation circuit. Connect a ceramic resonator
Main Clock Input XIN
Main Clock Output XOUT
Sub Clock Input XCIN
Sub Clock Output XCOUT
or crystal oscillator between XIN and XOUT. To apply external clock, apply it
to XIN and leave XOUT open
O
I
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
O
Connects the low-pass filter to the VCONT pin when using the PLL fre-
quency synthesizer. Connect P86 to VSS to stabilize the PLL frequency.
