6. Selecting a Clock

With the M32180T2-PTC, it is possible to select a clock
supply to the MCU by the clock select switch (SW1). Select
a clock supply as shown below.

However, when used with the M32180T2-PTC, the clock
cannot be supplied from the target system.

10 MHz:

Supplies the clock (X1: 10 MHz) on the M32180T2-
PTC board to the MCU.

SOCKET: Supplies the clock to the MCU from the socket

(X2) for mounting the oscillator on the
M32180T2-PTC board. By mounting the oscilla-
tor to the X2 socket of the MCU, it is possible to
change the operating frequency.

For more details on the connecting the X2 socket
and the MCU, see Figure 5 (right).
