An Excitation input loss to that channelwill trigger a bit failure (=1) on a per channel basis. Passing status (=0). Signal and/or Excitation Loss is indicatedafter 2 seconds. Signal and Excitation input monitoring is disabled during D3 or D0 Test. Any Excitation Statusfailure, transient or intermittent, will latch the Reference Status register. Reading any status bit will unlatch theentire register. Excitation Status is part of background testing and the status register may be checked or polled atany given time.REGISTER D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 FUNCTIONREFERNCE STATUS X X X X X X X X X X X X Ch4 Ch3 Ch2 Ch1 CHANNEL STATUS BITSignal Status Interrupt EnableType: binary wordRange: N/ARead/Write: R/WInitialized Value: 0Set the bit to enable interrupts for the corresponding channel.
