0x01F3—TSB FIFO Interrupt Enable Register (Used for DS1 Diagnostics)
These interrupts are only used for diagnostic testing. If the system clock driving the TSB interface fails, the
Transmit FIFOs will underflow and the Receive FIFOs will overflow. However, the TSB block will not respond
to reads of this register because of the failed system clock.

Interrupt enable for Transmit Payload FIFO Overflow. Do not enable this interrupt because the
FIFO will tend to run full during normal operation.
Interrupt enable for Transmit Payload FIFO Underflow. This interrupt should only be enabled
for DS1 operation. In other modes of operation, unused payload transmit FIFOs will stay
empty and generate continuous interrupts.
Interrupt enable for Receive Payload FIFO Overflow.
Interrupt enable for Receive Payload FIFO Underflow. Do not enable this interrupt because the
FIFO will tend to run empty during normal operation.
Interrupt enable for Transmit Overhead FIFO Overflow. Do not enable this interrupt because
the FIFO will tend to run full during normal operation.
Interrupt enable for Transmit Overhead FIFO Underflow. This interrupt should only be
enabled for DS1 operation. In other modes of operation, unused overhead transmit FIFOs will
stay empty and generate continuous interrupts.
Interrupt enable for Receive Overhead FIFO Overflow.
Interrupt enable for Receive Overhead FIFO Underflow. Do not enable this interrupt because
the FIFO will tend to run empty during normal operation.
A register value of 0x00 indicates no Transmit Payload Transmit FIFO Overflow errors.
Register values of 0x01–0x1C indicate which one of the 28 Transmit Payload FIFOs
overflowed. This register only reports the first FIFO to overflow. The subsequent overflow of
another FIFO will not be reported until this register is cleared.
