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.

Software Reset
1 = Reset. This bit is self-clearing; it isn't necessary to write "0" to exit reset.
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.
Reserved
Line Rate Control These bits determine the line bit rate relative to the reference clock, as well as the pre-driver
strength for the TXD+/- outputs.
00 Clock multiplier = 1x, pre-driver strength is “standard”
01 Clock multiplier = 2x, pre-driver strength is “standard”
10 Clock multiplier = 4x, pre-driver strength is “strong”
