USB block operations enabled bit (USBE)
This controller’s USB block operations can be enabled/disabled by writing to this bit. If the bit is modified from
"USBE=1" to "USBE=0", the controller initializes the bits shown in Table 2.5 and Table 2.6.
This bit can be modified when "SCKE=1".
When selecting the Host Controller function, write "DPRD=1", reject the LNST bit chattering, confirm that the USB bus
is stable, and then write "USBE=1".
