*1 : UART ch0/1 data input pins P45/SIN0, P72/SIN1/AN10 can be used as CMOS input by the communication
prescaler control register (CDRR).
*2 : Use a ceramic capacitor or a capacitor with equivalent frequency characteristics. On the V
CC
pin, connect a
bypass capacitor that has a larger capacity than that of C
S
. Refer to the following figure for connection of
smoothing capacitor C
S
.
