Transmit Pool Ready
A data block of up to 32 bytes can be written to the XFIFO.
An XPR interrupt will be generated in the following cases:
– after an XTF or XIF command, when one transmit pool is emptied and the frame is
– after an XTF together with an XME command is issued, when the whole
– after an XIF together with an XME command is issued, when the whole I frame has
Timer Interrupt
The internal timer and repeat counter has expired (see TIMR register).
C/I- or S/Q-Channel Change
A change in C/I channel 0, C/I channel 1 (only in IOM-2 TE mode) or S/Q channel has
been recognized. The actual value can be read from CIR0, CIR1 or SQRR.
Synchronous Transfer Interrupt
When programmed (STCR register), this interrupt is generated to enable the
processor to lock on to the IOM timing, for synchronous transfers.
Extended Interrupt
This bit indicates that one of six non-critical interrupts has been generated. The exact
interrupt cause can be read from EXIR.
A read of the ISTA register clears all bits except EXI and CISQ. EXI is cleared by
reading the EXIR register, CISQ is cleared by reading CIRR/CIR0.

Each interrupt source in the ISTA register can be selectively masked by setting to "1"
the corresponding bit in MASK. Masked interrupt status bits are not indicated when
ISTA is read. Instead, they remain internally stored and pending, until the mask bit is
reset to zero.
In the event of an extended interrupt and of a C/I- or S/Q-channel change, EXI and
CISQ are set in ISTA even if the corresponding mask bits in MASK are active, but no
interrupt (INT pin) is generated.
