This bit is set when at least one bit is set in GCI_EXIR register.
ISC Indication or S Channel Change
A change in the layer 1 indication code or multiframe S channel has been detected. The actual value can be read from CIR or
SQR registers.
T1EXP Timer 1 Expiration
Expiration occurs in the Timer 1.

Setting the bit to "1" masks the corresponding interrupt source in D_EXIR register. Masked interrupt status bits are read as zero.
They are internally stored and pending until the mask bits are zero.
All the interrupts in D_EXIR will be masked if the IMASK:D_EXI bit is set to "1".

XDOW Transmit Data Overwritten
At least one byte of data has been overwritten in the D_XFIFO. This bit is set by data overwritten condition and is cleared only by
XRST command.
XBZ Transmitter Busy
This bit indicates the D_HDLC transmitter is busy. The XBZ bit is active from the transmission of opening flag to the
transmission of closing flag.
DRDY D Channel Ready
This bit indicates the status of layer 1 D channel.
0: The layer 1 D channel is not ready. No transmission is allowed.
1: The layer 1 D channel is ready. Layer 2 can transmit data to layer 1.
Note : Due to design mistake, DRDY=1 does not mean S/T layer 1 is in F7 state. Software has to check “DRDY=1 and C/I
