Section 23 USB 2.0 Host/Function Module (USB)
(a)
Tables 23.15 and 23.16 show the buffer status. The buffer memory status can be confirmed using
the BSTS bit in DCPCTR and the INBUFM bit in PIPEnCTR. The access direction for the buffer
memory can be specified using either the DIR bit in PIPEnCFG or the ISEL bit in CFIFOSEL
(when DCP is selected).
The INBUFM bit is valid for PIPE0 to PIPE5 in the sending direction.
For an IN pipe uses double buffer, software can refer the BSTS bit to monitor the buffer memory
status of CPU side and the INBUFM bit to monitor the buffer memory status of SIE side. In the
case like the BEMP interrupt may not shows the buffer empty status because the CPU (DMAC)
writes data slowly, software can use the INBUFM bit to confirm the end of sending.
