B Message Mailbox 2: Channel [0—3]. These
registers will store the middle 16 bits of a valid
B message header. A maskable interrupt will be
generated if the SDL framer receives a B
message.
B Message Mailbox 3: Channel [0—3]. These
registers will store the last 16 bits of a valid B
message header. A maskable interrupt will be
generated if the SDL framer receives a B
message.
SDL Interrupt Mask Channel [0—3]. When
active (logic 1), the associated event/delta is
inhibited from contributing to the interrupt on a
per-channel basis.
Reserved. These bits must be written to their
reset default value (0x00).
