15.5.3 HcSoftwareReset register (W: A9H)
This register provides a means for software reset of the HC. To reset the HC, the
HCD must write a reset value of F6H to this register. On receiving this reset value,
the HC resets all the HC and OTG registers, except its buffer memory.
Table 74 contains the bit description of the register.
Code (Hex): A9 — write only
