Bits 7 to 0: RCLK Disable Upon LOS Register n (RDULRn). When this bit is set the RCLK for Channel n is
disabled upon a loss of signal and set as a low output. When reset or default RCLK will switch to MCLK upon a
loss of signal within 10ms.

Bit 1: INT Pin Mode (INTM). This bit determines the inactive mode of the INT pin. The INT pin always drives low
when active.
Bit 0: Clear On Write Enable (CWE). When this bit is set the clear on write is enabled for all the latched interrupt
status registers. The host processor must write a 1 to the latched interrupt status register bit position before the
particular bit will be cleared. Default for all the latched interrupt status registers is to clear on a read.
0 = Pin is high impedance when not active.
1 = Pin drives high when not active.
