The following description gives an example for the transmission of a 76 byte frame with
a selected block size of 32 byte:
• The host writes 32 bytes to the XFIFOD, issues an XTF command and waits for an
• The ISAC-SX TE immediately issues an XPR interrupt (as remaining XFIFOD space
• Due to the XPR interrupt the host writes the next 32 bytes to the XFIFOD, followed by
• As soon as the last byte of the first block is transmitted, the ISAC-SX TE releases an
• The host writes the remaining 12 bytes of the frame to the XFIFOD and issues the XTF
• After the last byte of the frame has been transmitted the ISAC-SX TE releases an XPR
