PROPRIETARY AND CONFIDENTIAL
warning of an underrun is given. The FULLE, LFILLE, OVRE, and UDRE bits
are all set to logic 1 so an interrupt on INTB is generated upon detection of a
FIFO full state, a FIFO depth below the lower limit threshold, a FIFO overrun, or
a FIFO underrun. The following procedure should be followed to transmit HDLC
packets:
1. Wait for a complete packet to be transmitted. Once data is available to be
2. Write the data byte to the TDPR Transmit Data register.
3. If all bytes of the packet have been written to the Transmit Data register, then
4. If there are more bytes in the packet to be sent, then go to step 2.
While performing steps 1 to 4, the processor should monitor for interrupts
generated by the TDPR. When an interrupt is detected, the TDPR Interrupt
Routine detailed in the following text should be followed immediately.
The TDPR will force transmission of the packet information when the FIFO depth
exceeds the threshold programmed with the UTHR[6:0] bits in the TDPR Upper
Transmit Threshold register. Unless an error condition occurs, transmission will
not stop until the last byte of all complete packets is transmitted and the FIFO
depth is at or below the threshold limit. The user should watch the FULLI and
LFILLI interrupts to prevent overruns and underruns.
TDPR Interrupt Routine:
Upon assertion of INTB, the source of the interrupt must first be identified by
reading the TEMAP-84 Master Interrupt Source register (0020H) followed by
reading one of the second level master interrupt source registers T1E1INT1,
T1E1INT2, T1E1INT3, T1E1INT4 or DS3INT. Once the source of the interrupt
has been identified as the TDPR in use, then the following procedure should be
carried out:
1. Read the TDPR Interrupt Status register.
2. If UDRI=1, then the FIFO has underrun and the last packet transmitted has
transmitted, then go to step 2.
set the EOM bit in the TDPR Configuration register to logic 1. Go to step 1.
been corrupted and needs to be retransmitted. When the UDRI bit transitions
to logic 1, one Abort sequence and continuous flags will be transmitted. The
TDPR FIFO is held in reset state. To re-enable the TDPR FIFO and to clear
the underrun, the TDPR Interrupt Status/UDR Clear register should be written
with any value.
