Make sure the USB clock source is correctly configured before setting this bit.
Unimplemented: Read as ‘0’
PPBRST: Ping-Pong Buffers Reset bit
1 = Reset all Ping-Pong Buffer Pointers to the Even Buffer Descriptor (BD) banks
0 = Ping-Pong Buffer Pointers are not being reset
SE0: Live Single-Ended Zero Flag bit
1 = Single-ended zero is active on the USB bus
0 = No single-ended zero is detected
PKTDIS: Packet Transfer Disable bit
1 = SIE token and packet processing are disabled, automatically set when a SETUP token is received
0 = SIE token and packet processing are enabled
USBEN: USB Module Enable bit
1 = USB module and supporting circuitry are enabled (device attached)
0 = USB module and supporting circuitry are disabled (device detached)
RESUME: Resume Signaling Enable bit
1 = Resume signaling is activated
0 = Resume signaling is disabled
SUSPND: Suspend USB bit
1 = USB module and supporting circuitry are in Power Conserve mode, SIE clock is inactive
0 = USB module and supporting circuitry are in normal operation, SIE is clocked at the configured rate
Unimplemented: Read as ‘0’
