0: Disable
1: Enable

  Unused

Bits 27 : 26

  OHCI_COUNT_SELECT

Bit 25
R/W
0x0

1: Simulation mode, the counters will be much shorter then real time
0: Normal mode, the counters will count full time

  SIMULATION_MODE

Bit 24
R/W
0x0

1: Set PHY in a non-driving mode so the EHCI can detect device connection, this is used only for simulation
0: No effect

  Unused

Bits 23 : 21

  EHCI_HS_FORCE

Bit 20
R/W
0x0

Set 1 to this field force the ehci enter the high speed mode during bus reset.
This field only valid when the bit 1 is set.

  Unused

Bit 19

  RESUME_SE0_TRANS

Bit 18
R/W
0x0

1: within 2us of the resume-K to SE0 transition
0: random time value of the resume-K to SE0 transition

  Unused

Bits 17 : 13

  PP2VBUS

Bit 12
R/W
0x0

1: ULPI wrapper interface will automatically set or clear DrvVbus register in
ULPI PHY according to the port power status form the root hub
0: ULPI wrapper will ignore the difference between power status of root
hub and ULPI PHY

  INCR16_ENA

Bit 11
R/W
0x0

AHB Master interface INCR16 enable
1: Use INCR16 when appropriate
0: do not use INCR16,use other enabled INCRX or unspecified length burst

  INCR8_ENA

Bit 10
R/W
0x0

AHB Master interface INCR8 enable
1: Use INCR8 when appropriate
0: do not use INCR8,use other enabled INCRX or unspecified length burst

  INCR4_ENA

Bit 9
R/W
0x0

AHB Master interface burst type INCR4 enable
1: Use INCR4 when appropriate
0: do not use INCR4,use other enabled INCRX or unspecified length burst

  INCRX_ALIGN_ENA

Bit 8
R/W
0x0

AHB Master interface INCRX align enable
1: start INCRx burst only on burst x-align address
0: Start burst on any double word boundary
Note: This bit must enable if any bit of 11:9 is enabled

R/W
0x0

0: disable
1:enable

  Unused

Bit 1

  ULPI_BYPASS_ENABLE

Bit 0
R/W
0x0

1: Enable UTMI interface, disable ULPI interface
0: Enable ULPI interface, disable UTMI interface
