6. Selecting a Clock


With the M32192T2-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 M32192T2-PTC, the clock
cannot be supplied from the user system.

(1) 20 MHz

Supplies the clock (X1: 20 MHz) on the M32192T2-PTC

board to the MCU.

(2) SOCKET

Supplies the clock to the MCU from the socket (X2) for

mounting an oscillator on the M32192T2-PTC board. By

mounting an oscillator to the X2 socket of the MCU, it is

possible to change the operating frequency.

Figure 6.1 shows the connecting the X2 socket and the

MCU.
