PIC18F2455/2550/4455/4550
REGISTER 17-2:
There are 6 signals from the module to communicate
with and control an external transceiver:
• VM: Input from the single-ended D- line
• VP: Input from the single-ended D+ line
• RCV: Input from the differential receiver
• VMO: Output to the differential line driver
• VPO: Output to the differential line driver
• UOE: Output enable

If UTRDIS is set, the UOE signal will be active independent of the UOEMON bit setting.
The UPUEN, UTRDIS and FSEN bits should never be changed while the USB module is enabled. These
values must be preconfigured prior to enabling the module.
This bit is only valid when the on-chip transceiver is active (UTRDIS = 0); otherwise, it is ignored.
UTEYE: USB Eye Pattern Test Enable bit
1 = Eye pattern test enabled
0 = Eye pattern test disabled
UOEMON: USB OE Monitor Enable bit
1 = UOE signal active; it indicates intervals during which the D+/D- lines are driving
0 = UOE signal inactive
Unimplemented: Read as ‘0’
UPUEN: USB On-Chip Pull-up Enable bit
1 = On-chip pull-up enabled (pull-up on D+ with FSEN = 1 or D- with FSEN = 0)
0 = On-chip pull-up disabled
UTRDIS: On-Chip Transceiver Disable bit
1 = On-chip transceiver disabled; digital transceiver interface enabled
0 = On-chip transceiver active
FSEN: Full-Speed Enable bit
1 = Full-speed device: controls transceiver edge rates; requires input clock at 48 MHz
0 = Low-speed device: controls transceiver edge rates; requires input clock at 6 MHz
PPB1:PPB0: Ping-Pong Buffers Configuration bits
11 = Even/Odd ping-pong buffers enabled for Endpoints 1 to 15
10 = Even/Odd ping-pong buffers enabled for all endpoints
01 = Even/Odd ping-pong buffer enabled for OUT Endpoint 0
00 = Even/Odd ping-pong buffers disabled

The VPO and VMO signals are outputs from the SIE to
the external transceiver. The RCV signal is the output
from the external transceiver to the SIE; it represents
the differential signals from the serial bus translated
into a single pulse train. The VM and VP signals are
used to report conditions on the serial bus to the SIE
that can’t be captured with the RCV signal. The
combinations of states of these signals and their
interpretation are listed in Table 17-1 and Table 17-2.
