Unused. Read all 0’s.
Reserved. Write 0 for normal operation
Reserved. Write 0 for normal operation
Write 0 for normal operation, 1 to tristate parity.
Parity Bit. EVEN parity is selected when this bit is set. ODD parity is selected when this bit
is cleared.
User Defined Byte. This byte is inserted into the sixth byte of the header when cells are
being output in 16-bit mode.
Reserved.
Stand-by mode bit. When set the RX Utopia will continue to operate normally, but all of the
interface’s output pins will be in high impedance mode.
Override for the tristate of the cell available. When set URxClav’s value is always driven.
Override for the tristate of the UTOPIA data, start of cell, and UTOPIA parity signals.
When set URxData’s, URxSOC’s, and URxPar’s values are always driven.
16/8-bit mode selection bit for the RX UTOPIA data bus. When set the RX UTOPIA
interface is operating in 8-bit mode, when reset it is operating in 16-bit mode.
Reserved. Write 0 for normal operation.
Reset UTOPIA RX state machines when set to 1.
Reserved. Write 0 for normal operation.
