Device n SOF/EOP Count Register [W]

Table 73. Device n SOF/EOP Count Register
Register Description
The Device n SOF/EOP Count register is written with the time
expected between receiving a SOF/EOP. If the SOF/EOP
counter expires before an SOF/EOP is received, an SOF/EOP
Timeout Interrupt can be generated. The SOF/EOP Timeout
Interrupt Enable and SOF/EOP Timeout Interrupt Flag are
located in the Device n Interrupt Enable and Status registers
respectively.
Set the SOF/EOP count slightly greater than the expected
SOF/EOP interval. The SOF/EOP counter decrements at a
12 MHz rate. Therefore, in the case of an expected 1 ms
SOF/EOP interval, the SOF/EOP count is set slightly greater
than 0x2EE0.
Count (Bits [13:0])
The Count field contains the current value of the SOF/EOP down
counter. At power up and reset, this value is set to 0x2EE0 and
for expected 1 ms SOF/EOP intervals, this SOF/EOP count is
increased slightly.
OTG Control Register [0xC098] [R/W]
Table 75. OTG Control Register
Register Description
The OTG Control register allows control and monitoring over the
OTG port on Port1A. Note that the D± pull up and pull down bits
override the setting in the USB 0 Control register for this port.

OTG Control Registers
There is one register dedicated for On-The-Go operation. This
register is covered in this section and summarized in
Table 74. OTG Register
VBUS Pull-up Enable (Bit 13)
The VBUS Pull-up Enable bit enables or disables a 500 ohm pull
up resistor onto OTG VBus.
1: 500 ohm pull up resistor enabled
0: 500 ohm pull up resistor disabled
