R/W

0 = OSC

Transmit Line Clock (or Loop Timing Mode)

When set to 0, the OSC input is used as the transmit like clock. When set to 1, the recovered receive clock is used as

the transmit line clock.

Note:

When set to "1", these bits mask the corresponding interrupt pin (

INT). When set to "0", the interrupts are unmasked. These interrupts correspond

to the interrupt status bits in the interrupt Status Registers.
