4.3
Table 4.2 shows the relationship between the combinations of the mode control pins (MD_CLK2
and MD_CLK0) and the clock operating modes. Table 4.3 shows the usable frequency ranges in
the clock operating modes.

The frequency of the signal received from the EXTAL pin or crystal oscillator is quadrupled
by the PLL circuit 2 before it is supplied to the LSI as the clock signal. This allows a crystal
with a lower frequency to be used. Either a crystal resonator with a frequency in the range
from 8 to 10 MHz or an external signal in the same frequency range input on the EXTAL pin
can be used. When the CK output is in use, the frequency range is from 32 to 40 MHz. When
an input signal on the EXTAL pin is in use, the XTAL pin should be left open.
