6. Selecting a Clock
With the M32176T-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 M32176T-PTC, the clock cannot
be supplied from the user system.
(1)
10 MHz
Supplies the clock (X1: 10 MHz) on the M32176T-PTC
board to the MCU.
(2)
SOCKET
Supplies the clock to the MCU from the socket (X2) for
mounting an oscillator on the M32176T-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.
