14.2
The operation of the USB module is configured and
managed through three control registers. In addition, a
total of 22 registers are used to manage the actual USB
transactions. The registers are:
• USB Control register (UCON)
• USB Configuration register (UCFG)
• USB Transfer Status register (USTAT)
• USB Device Address register (UADDR)
• Frame Number registers (UFRMH:UFRML)
• Endpoint Enable registers 0 through 15 (UEPn)
14.2.1
The USB Control register (Register 14-1) contains bits
needed to control the module behavior during transfers.
The register contains bits that control the following:
• Main USB Peripheral Enable
• Ping-Pong Buffer Pointer Reset
• Control of the Suspend Mode
• Packet Transfer Disable

USB Status and Control
USB CONTROL REGISTER (UCON)
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 not being reset
SE0: Live Single-Ended Zero Flag bit
1 = Single-ended zero active on the USB bus
0 = No single-ended zero detected
PKTDIS: Packet Transfer Disable bit
1 = SIE token and packet processing disabled, automatically set when a SETUP token is received
0 = SIE token and packet processing enabled
USBEN: USB Module Enable bit
1 = USB module and supporting circuitry enabled (device attached)
0 = USB module and supporting circuitry disabled (device detached)
RESUME: Resume Signaling Enable bit
1 = Resume signaling activated
0 = Resume signaling disabled
SUSPND: Suspend USB bit
1 = USB module and supporting circuitry in Power Conserve mode, SIE clock inactive
0 = USB module and supporting circuitry in normal operation, SIE clock clocked at the configured rate
Unimplemented: Read as ‘0’
PPBRST

U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
USBEN
R/W-0
In addition, the USB Control register contains a status
bit, SE0 (UCON<5>), which is used to indicate the
occurrence of a single-ended zero on the bus. When
the USB module is enabled, this bit should be
monitored to determine whether the differential data
lines have come out of a single-ended zero condition.
This helps to differentiate the initial power-up state from
the USB Reset signal.
The overall operation of the USB module is controlled
by the USBEN bit (UCON<3>). Setting this bit activates
the module and resets all of the PPBI bits in the Buffer
Descriptor Table to ‘0’. This bit also activates the on-
chip voltage regulator, if enabled. Thus, this bit can be
used as a soft attach/detach to the USB. Although all
status and control bits are ignored when this bit is clear,
the module needs to be fully preconfigured prior to
setting this bit.
