The Device n Endpoint n Count Result register is a
memory-based register that must be initialized to 0x0000 before
USB Device operations are initiated. After initialization, do not
write to this register again.
Result (Bits [15:0])
The Result field contains the differences in bytes between the
received packet and the value specified in the Device n Endpoint
n Count register. If an overflow condition occurs, Result [15:10]
is set to ‘111111’, a 2’s complement value indicating the
Device n Port Select Register [R/W]

Table 68. Device n Port Select Register
Register Description
The Device n Port Select register selects either port A or port B
for the static device port.

Table 69. Device n Interrupt Enable Register
Register Description
The Device n Interrupt Enable register provides control over
device related interrupts including eight different endpoint inter-
rupts.

additional byte count of the received packet. If an underflow
condition occurs, Result [15:0] indicates the excess bytes count
(number of bytes not used).
Reserved
Write all reserved bits with ‘0’.
Port Select (Bit 14)
The Port Select bit selects which of the two ports is enabled.
1: Port 1B or Port 2B is enabled
0: Port 1A or Port 2A is enabled
VBUS Interrupt Enable (Bit 15)
The VBUS Interrupt Enable bit enables or disables the OTG
VBUS interrupt. When enabled, this interrupt triggers on both the
rising and falling edge of VBUS at the 4.4V status (only
