12.12.4 Handling the Receive Header

12.12.5 Handling Interrupts

All interrupts are masked on startup, and should not be enabled until the link initializes.

12.12.6 Bypass Function

Functional block transmit and receive functions can be disabled independently (or together) by

writing a ‘1’ to:

• The LSB (TX_BYPASS) of the Transmit Control register to enable transmit bypass.

• The LSB (RX_BYPASS) of the Receive Control register to enable receive bypass.

When in bypass mode, message FIFO rams are disabled and the ILC functions as a 2-stage

pipeline. When TX_BYPASS is set, writes to the transmit FIFO are ignored and when

RX_BYPASS is set, reads from the receive FIFO return random data.
