After setting the corresponding bit, the selected defect is inserted into the transmit data
stream at the next possible position. After defect insertion is completed, the bit is reset
automatically.

Interrupt Mask Register
Each interrupt source can generate an interrupt signal on port INT
(characteristics of the output stage are defined by register IPC). A “1”
in a bit position of IMR(5:0) sets the mask active for the interrupt
status in ISR(5:0). Masked interrupt statuses neither generate a
signal on INT, nor are they visible in register GIS. Moreover, they are
- not displayed in the interrupt status register if bit GCR.VIS is cleared
- displayed in the interrupt status register if bit GCR.VIS is set
Note: After reset, all interrupts are disabled.
