(E) = Even transaction buffer, (O) = Odd transaction buffer
For buffer descriptor registers, n may have a value of 0 to 31. For the sake of brevity, all 32 registers are
shown as one generic prototype. All registers have indeterminate Reset values (xxxx xxxx).
Bits 5 through 2 of the BDnSTAT register are used by the SIE to return PID<3:0> values once the register
is turned over to the SIE (UOWN bit is set). Once the registers have been under SIE control, the values
written for DTSEN and BSTALL are no longer valid.
Prior to turning the buffer descriptor over to the SIE (UOWN bit is cleared), bits 5 through 2 of the
BDnSTAT register are used to configure the DTSEN and BSTALL settings.
This bit is ignored unless DTSEN = 1.
