Register Name:
Register Description:
Register Address:
Bit #
Name
Default
This register is a global resource and is mapped into address 06h in every framer in the device. In both interrupt-based and polling-based
device servicing strategies, the host processor should read this register and the ISR2 register first to determine which framers require servicing.
Bit 0: Interrupt 1 (INT1). This bit is set when framer 1 is driving the INT pin.
Bit 1: Interrupt 2 (INT2). This bit is set when framer 2 is driving the INT pin.
Bit 2: Interrupt 3 (INT3). This bit is set when framer 3 is driving the INT pin.
Bit 3: Interrupt 4 (INT4). This bit is set when framer 4 is driving the INT pin.
Bit 4: Interrupt 4 (INT5). This bit is set when framer 5 is driving the INT pin.
Bit 5: Interrupt 4 (INT6). This bit is set when framer 6 is driving the INT pin.
Bit 6: Interrupt 4 (INT7). This bit is set when framer 7 is driving the INT pin.
Bit 7: Interrupt 4 (INT8). This bit is set when framer 8 is driving the INT pin.

This register is a global resource and is mapped into address 07h in every framer in the device. In both interrupt-
based and polling-based device servicing strategies, the host processor should read this register and the ISR1
register first to determine which framers require servicing.
Bit 0: Interrupt 9 (INT9). This bit is set when framer 9 is driving the INT pin.
Bit 1: Interrupt 10 (INT10). This bit is set when framer 10 is driving the INT pin.
Bit 2: Interrupt 11 (INT11). This bit is set when framer 11 is driving the INT pin.
Bit 3: Interrupt 12 (INT12). This bit is set when framer 12 is driving the INT pin.
