HS0/2 : HDLC Interrupt Queue Size
TBFS : Time Base running with Frame Synchronisation signal
VI.29 - Interrupt Register
This register is read only.
When this register is read by the microprocessor, this register is reset (0000) .
If not masked, each bit at “1” generates “1” on INT0 pin.
Bit 0 and bit 5 to 10 are common to 64 HDLC controllers.

These three bits define the size of HDLC status Interrupt Queue in external memory for each
channel.
The location is IBA+256 (see The Initiate Block Address (IBA))
TBFS=1, the Time Base defined by the Timer Register (see page 84) is running on the rising
edge of Frame Synchronisation signal.
TBFS=0, the Time Base defined by the Timer Register is running on the rising edge of MCLK
signal.

HDLC = 1, Tx HDLC or Rx HDLC has generated an interrupt The status is in the HDLC
queue.
C/IRX = 1, Rx Command/Indicate has generated an interrupt. The status is in the HDLC
queue.
MRX = 1, one Rx MONITOR CHANNEL has generated an interrupt. The status is in the Rx
Monitor Channel queue
MTX = 1, one or several Tx MONITOR CHANNELS have generated an interrupt. Transmit
Monitor Interrupt Register (TMIR) indicates the Tx Monitor Channels which have generated
this interrupt.
ICOV = 1, One of three circular interrupt memories is completed.
