Programmable Registers
32.4.7 UTMI Debug Status Register 0 (HW_USBPHY_DEBUG0_STATUS)
The UTMI Debug Status Register 0 holds multiple views for counters and status of state
machines. This is used in conjunction with the HW_USBPHY_DEBUG1.DBG_ADDRESS
field to choose which function to view. The default is described in the bit fields below and
is used to count errors.

UTMI_RXERROR_FAIL_COUNT
Delay in between the detection of squelch to the reset of high-speed RX.
Reserved.
Set this bit to allow a countdown to transition in between TX and RX.
Delay in between the end of transmit to the beginning of receive. This is a Johnson count value
and thus will count to 8.
Reserved.
Set bit 5 to 1 to override the control of the USB_DP 15-KOhm pulldown.
Set bit 4 to 1 to override the control of the USB_DM 15-KOhm pulldown.
Clear to 0 to disable.
Set bit 3 to 1 to pull down 15-KOhm on USB_DP line.
Set bit 2 to 1 to pull down 15-KOhm on USB_DM line.
Clear to 0 to disable.
Use holding registers to assist in timing for external UTMI interface.
Once OTG ID from HW_USBPHY_STATUS_OTGID_STATUS, use this to hold the value. This
is to save power for the comparators that are used to determine the ID status.
