VI.29 - Interrupt Register

IR (38)H

This register is read only.

When this register is read by the microprocessor, this register is reset (0000)Η.

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.

HS0/2 : HDLC Interrupt Queue Size

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 : Time Base running with Frame Synchronisation signal

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

: HDLC INTERRUPT

HDLC = 1, Tx HDLC or Rx HDLC has generated an interrupt The status is in the HDLC

queue.

C/IRX

: Command/Indicate Rx Interrupt

C/IRX = 1, Rx Command/Indicate has generated an interrupt. The status is in the HDLC

queue.

MRX

: Rx MONITOR CHANNEL INTERRUPT

MRX = 1, one Rx MONITOR CHANNEL has generated an interrupt. The status is in the Rx

Monitor Channel queue

MTX

: Tx MONITOR CHANNEL INTERRUPT

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

: INTERRUPT CIRCULAR OVERLOAD

ICOV = 1, One of three circular interrupt memories is completed.
