12.2.1.1
The USB module supports either an internal or external USB transceiver. USB_D+ and USB_D- drive
USB cable D+ and D- lines, respectively. With additional external protection circuitry (see
“Recommended USB Protection
Specification, Rev. 1.1. Transceiver performance specifications are described in the Chapter 7 of the
Universal Serial Bus Specification. See note on page , [p. 12-1].
When the internal transceiver is selected, (USBEPCTL0[AFEEN] is cleared), the driven outputs can be
observed by using the parallel port A if these pins are configured for USB, using the PACNT register,
