Transfer Normal Completion Interrupt Flag Register 0 (TSFR0)

TSFR0 provides status flags indicating that the host input or host output transaction of each USB
function core endpoint has been completed normally.
The normal completion of a transaction can be detected by an ACK handshake reception in host
input transfer or by an ACK handshake transmission in host output transfer.
TSFR0 is initialized to H'00 by a system reset or function software reset (see section 18.3.16, USB
Control Registers 0 and 1 (USBCR0, USBCR1)).
