Reception of an HDLC Frame
Transmit Frame Processing
After checking the XFIFO status by polling the Transmit FIFO Write Enable (XFW) bit or after a
Transmit Pool Ready (XPR) interrupt, up to 32 bytes may be entered by the microcontroller in the
XFIFO. Transmission of an HDLC frame is started when the Transmit HDLC Frame (XHF)
command is issued. The HDLC controller will request another data block by an XPR interrupt if there
are no more than 32 bytes in the XFIFO and the frame close command bit (Transmit Message End
XME) has not been set. When XME is set, all remaining bytes in the XFIFO are transmitted, the
CRC field and the closing flag of the HDLC frame are appended and the controller generates a new
XPR interrupt (figure19).
