10.25.3 SCK_COUNT
Transfer Count Register
Only write to this register when socket is in suspend state or disabled state.
31:0 TRANS_COUNT[31:0] The number of bytes or buffers (depends on unit bit in SCK_STATUS) that have been transferred
through this socket so far. If trans_size is >0 and trans_count >= trans_size the ‘trans_done’ bits in
SCK_STATUS is both set. If SCK_STATUS.susp_trans=1 the socket is also suspended and the ‘sus-
pend’ bit set. This count is updated only when a descriptor is completed and the socket proceeds to
the next one.
Exception: When socket suspends with PARTIAL_BUF=1, this value is (incorrectly) incremented by 1
(UNIT=1) or DSCR_SIZE.BYTE_COUNT (UNIT=0). Firmware must correct this before resuming the
socket.
