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 XFIFOx, issues an XTF command and waits for an
• The ISAC-SX immediately issues an XPR interrupt (as remaining XFIFOx space is not
• Due to the XPR interrupt the host writes the next 32 bytes to the XFIFOx, followed by
• As soon as the last byte of the first block is transmitted, the ISAC-SX releases an XPR
• The host writes the remaining 12 bytes of the frame to the XFIFOx and issues the XTF
• After the last byte of the frame has been transmitted the ISAC-SX releases an XPR
