Description
I VCC1
O VCC1
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
Sub clock output
XCIN
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.

output function
Notes:
1. Contact the oscillator manufacturer regarding the oscillation characteristics.
2. TXD2, SDA2, and SCL2 are N-channel open drain output pins. TXDi (i = 0, 1, 5 to 7), SDAi, and SCLi can be
selected as CMOS output pins or N-channel open drain output pins by a program.
