Receive FIFO Overflow.
Function
Note: When set to "1", these bits mask the corresponding interrupts going to the interrupt pin (INT). When set to "0", the interrupts are
unmasked. These interrupts correspond to the interrupt status bits in the Interrupt Status Registers.
Enhanced Control Register
Address:0x08
Bit Type Initial State
Function
7W
0 = not reset
Software Reset 1 = Reset. This bit is self-clearing; it isn't necessary to write ""0"" to exit reset.
6 R/W 0 = OSC
Transmit Line Clock (or Loop Timing Mode) When set to 0, the OSC input is used as the transmit line clock. When
set to 1, the recovered receive clock is used as the transmit line clock.
5 R/W 0
Reserved
4-0 R/W 00000
Utopia Port Address These bits determine the 5-bit address of the Utopia port for both receive and transmit.

Note: Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliabilty.
