2.4.1.3 INTMSK—Interrupt Mask (HDLC)
Each event defined in the interrupt circular queue entry maps directly to a bit in INTMSK
as shown in Figure 2-9. There is one mask bit for each event—NID (bit 2), IDL (bit 3),
MRF (bit 10), UN (bit 11), RXF (bit 12), BSY (bit 13), TXB (bit 14) and RXB (bit 15). Bits
that do not map to an event are reserved. Reserved bits must be set to zero. Refer to
Chapter 4, “QMC Exceptions,” for more detail.
This register is initialized by the host prior to operation.

Address type—This field contains the address type for the transmitter DMA channel for data
buffers in external memory (transmit buffers). Address types are needed by the memory
controller to decode a correct memory cycle and activate the correct handshaking.
