APINTERVAL
Control of the Aged Priority (priority inversion) for DMA accesses:
RW
0x00
When set to 0x0, the aged priority is disabled
When set to another value, this controls how often the priority is
adjusted: every APInterval cycles, the priority of the port is
decreased until the associated request is accepted or the priority of
the port equals 0. The priority of the port is reinitialized to the
transaction priority each time a new VBUS command is generated,
i.e. the last one has been accepted.
0x0:
Aged Priority Disabled:
There is no aged priority in SCR. DMA transaction keeps
the fixed priority defined internally, and has to wait for the
bus to be freed by higher priority initiators
