DBGMOD
Logic 1 enables all interrupts. Bus reset value: unchanged.
Logic 1 enables debug mode, in which all NAKs and errors will
generate an interrupt. Logic 0 selects normal operation, in which
interrupts are generated on every ACK (bulk endpoints) or after
every data transfer (isochronous endpoints). Bus reset value:
unchanged.

SOFTCT
Logic 1 enables SoftConnect. This bit is ignored if EXTPUL = 1
in the DcHardwareConfiguration register (see Table 114). Bus
reset value: unchanged.
Remark: In the OTG mode, this bit is ignored. The LOC_CONN
bit of the OtgControl register controls the pull-up resistor on the
OTG_DP1 pin.
16.1.4 DcHardwareConfiguration register (R/W: BBH/BAH)
This command is used to access the DcHardwareConfiguration register, which
consists of two bytes. The first (lower) byte contains the device configuration and
control values, the second (upper) byte holds the clock control bits and the clock
division factor. The bit allocation is given in Table 114. A bus reset will not change any
of the programmed bit values.
The DcHardwareConfiguration register controls the connection to the USB bus, clock
activity and power supply during the ‘suspend’ state, as well as output clock
frequency, DMA operating mode and pin configurations (polarity, signalling mode).
Code (Hex): BA/BB — write or read DcHardwareConfiguration register
Transaction — write or read 2 bytes (code or data)
