Clock supply

CAUTION

Make sure that power to the product is turned off and the power plug is

Prohibition disconnected from outlets before mounting crystal unit or handling switches or jumpers. Doing so may result in device problems or electric shock.

The emulator supplies clock pulses to the evaluation MCU.

Figure 3.2-1"Mounting a crystal unit" shows how to mount a crystal unit in IC sockets for a crystal unit on the emulator. Figure 3.2-2"Configuration of peripheral circuits for the clock circuit" shows the configuration of peripheral circuits for the clock circuit. Figure 3.2-3"Examples of jumper settings for subclock selection" shows examples of jumper settings for subclock selection. Table 3.2-1"Settings for main clock selection" lists settings of main clock selection switches. Table 3.2-2"Settings for subclock selection" lists settings for subclock selection.
