Figure 3.6.5 shows an example of USB connection (assuming that NOR Flash is
program memory)
Set the oscillation frequency for the X1 and X2 pins to 24.00 MHz (± 100 ppm) when
booting using USB.
The USB of this microcontroller supports high-speed communications. However, if the
USB host does not support high-speed communications (USB 1.1 or older), full-speed
communications will be carried out.
(The boot ROM function does not support clock supply from the USB clock pin X1USB.)
(For cautions on using the USB, refer to the chapter on the USB.)
Although there are four types of USB transfer, the following two types are used for the
boot function.
Control Transfer
