18.3.1
Unlike device level interrupts, the USB OTG interrupt
status flags are not freely writable in software. All USB
OTG flag bits are implemented as hardware set only
bits. Additionally, these bits can only be cleared in

The following section describes how to perform a com-
mon Device mode task. In Device mode, USB transfers
are performed at the transfer level. The USB module
automatically performs the status phase of the transfer.

Note:
Enable the USB module by setting the USBEN
bit (U1CON<0>).
Set the OTGEN bit (U1OTGCON<2>) to enable
OTG operation.
Enable the endpoint zero buffer to receive the
first setup packet by setting the EPRXEN and
EPHSHK bits for Endpoint 0 (U1EP0<3,0> = 1).
Power up the USB module by setting the
USBPWR bit (U1PWRC<0>).
Enable the D+ pull-up resistor to signal an attach
by setting DPPULUP bit (U1OTGCON<7>).
Throughout this data sheet, a bit that can
only be cleared by writing a ‘1’ to its loca-
tion is referred to as “Write 1 to clear”. In
register descriptions, this function is
indicated by the descriptor, “K”.
