1: Input above threshold
CMPIN1 (Comparison Result for Input 1). Same as CMPIN0 for KBSIN1.
CMPIN2 (Comparison Result for Input 2). Same as CMPIN0 for KBSIN2.
CMPIN3 (Comparison Result for Input 3). Same as CMPIN0 for KBSIN3.
CMPIN4 (Comparison Result for Input 4). Same as CMPIN0 for KBSIN4.
CMPIN5 (Comparison Result for Input 5). Same as CMPIN0 for KBSIN5.
CMPIN6 (Comparison Result for Input 6). Same as CMPIN0 for KBSIN6.
CMPIN7 (Comparison Result for Input 7). Same as CMPIN0 for KBSIN7.
THRSHD5-THRSHD0 (Comparison Threshold Data). Data to be used by the D/A converter in Threshold
Comparison Burst and Low Power Threshold Comparison modes. All eight inputs are compared with the resulting
voltage value.
