Bit #
Name
Default
Bits 7 to 0: RCLK Disable Upon LOS Register n (RDULRn). When this bit is set the RCLKn is disabled upon a
loss of signal and set as a low output. When reset, RCLKn switches to MCLK within 10ms of a loss of signal.

Register Description:
Register Address:
Bit #
Name
Default
Bit 1: INT Pin Mode (INTM). This bit determines the inactive mode of the INTB pin. The INTB pin always drives low
when active.
Bit 0: Clear-On-Write Enable (CWE). When this bit is set, 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 is cleared.
0 = Pin is high impedance when not active.
1 = Pin drives high when not active.
