Bit 21 NOVBUSSENS: V
BUS
sensing disable option
When this bit is set, V
BUS
is considered internally to be always at V
BUS
valid level (5 V). This
option removes the need for a dedicated V
BUS
pad, and leave this pad free to be used for
other purposes such as a shared functionality. V
BUS
connection can be remapped on
another general purpose input pad and monitored by software.
This option is only suitable for host-only or device-only applications.
