$1A: Level Detection Threshold Limit Value (Read/Write)
LDTH[7:0]: Level detection threshold value. If THOPT bit in Detection Control Register is “0”, it is unsigned 7 bits value and
LDTH[7] should be “0”. If THOPT bit is “1”, it is signed 8 bits value.
$1B: Pulse Detection Threshold Limit Value (Read/Write)
PDTH[6:0]: Pulse detection threshold value (unsigned 7 bits).
XPDTH: This bit should be “0”.
$1C: Pulse Duration Value (Read/Write)
Min: PD[7:0] = 4’h01 = 0.5 ms
Max: PD[7:0] = 4’hFF = 127 ms
1 LSB = 0.5 ms
$1D: Latency Time Value (Read/Write)
Min: LT[7:0] = 8’h01 = 1 ms
Max: LT[7:0] = 8’hFF = 255 ms
1 LSB = 1 ms
$1E: Time Window for 2nd Pulse Value (Read/Write)
Min: TW[7:0] = 8’h01 = 1 ms (Single pulse detection)
Max: TW[7:0] = 8’hFF = 255 ms
1 LSB = 1 ms
