The oscillator constants shown above are reference values based on evaluation in a
specific environment by the resonator manufacturer. If it is necessary to optimize
the oscillator characteristics in the actual application, apply to the resonator
manufacturer for evaluation on the implementation circuit.
When doing so, check the conditions for using the RMC register, and whether to
enter or exit the STOP mode.
The oscillation voltage and oscillation frequency only indicate the oscillator
characteristic. Use the 78K0R/KE3 so that the internal operation conditions are
within the specifications of the DC and AC characteristics.
P02 to P04 do not output high level in N-ch open-drain mode.
The maximum value of V

For P122/EXCLK, the value of V
external clock mode.
Make sure to satisfy the DC characteristics of EXCLK in external clock input mode.
When using UART1, select the normal input buffer for RxD1 and the normal output
mode for TxD1 by using the PIM0 and POM0 registers.
When using CSI10, select the normal input buffer for SI10 and the normal output
mode for SO10 and SCK10 by using the PIM0 and POM0 registers.
When using CSI10, select the normal input buffer for SI10 and SCK10 and the
normal output mode for SO10 by using the PIM0 and POM0 registers.
Select the normal input buffer and the N-ch open drain output (V
for SDA10 and the normal output mode for SCL10 by using the PIM0 and POM0
registers.
Select the TTL input buffer for RxD1 and the N-ch open drain output (V
mode for TxD1 by using the PIM0 and POM0 registers.
