The SOF/EOP count must be set 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 must be set slightly greater then
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 should be increased slightly.
Reserved
All reserved bits must be written as ‘0’.
8.6
There is one register dedicated for OTG operation. This register is covered in this section and summarized in
Figure 8-39
.
OTG Control Registers
8.6.1
OTG Control Register [0xC098] [R/W]
Figure 8-40. OTG Control Register
Register Description
The OTG Control register allows control and monitoring over the OTG port on Port1A.
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
Receive Disable
(Bit 12)
The Receive Disable bit enables or powers down (disables) the OTG receiver section.
1:
OTG receiver powered down and disabled
0:
OTG receiver enabled
