Figure 36. Location Of Access Points On The C18 - Motorola c18 Developer's Manual

Customer applications that have already been completed, which had not implemented the above preparations, will need to access
relevant signals on their host boards (such as AUDIO_IN, which is available for the 28-pin connector), or directly on the c18
(using the USB_D+, USB D- and USB_VBUS pins). The location of relevant access points on the c18 is shown in Figure 36.
USB_VBUS should be accessed at the pin #1 pad of the 36-pin connector. USB_D+ and USB_D- should be accessed at the pads
of the resistors marked in red.
