It is used for the case of receiving-error of SOF-token.
This function is set by COMMAND-register.
By reset, this bit is initialized to "0".
show the status whether a frame-number shown FRAME-register
is correct or not. At the LOST-status, a correct frame-number
is invalid.
If this register is "VALID", it means a value in FRAME-register
is correct.
If this register is "BEFORE", when using SOF auto-generation,
BEFOREcondition displies it from USB-host-contreoller inside that
from SOF generation time to receive SOF-token. Right value is it in
frame-number that value advanced one value from value displied to
FRAME register.

The USBC compares this register and address in all packet-ID and
