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.
PDTH[6:0]: Pulse detection threshold value (unsigned 7 bits).
XPDTH: This bit should be “0”.
Min: PD[7:0] = 4’h01 = 0.5 ms
Max: PD[7:0] = 4’hFF = 127 ms
1 LSB = 0.5 ms
Min: LT[7:0] = 8’h01 = 1 ms
Max: LT[7:0] = 8’hFF = 255 ms
1 LSB = 1 ms
Min: TW[7:0] = 8’h01 = 0 ms (Single pulse detection)
Max: TW[7:0] = 8’hFF = 255 ms
1 LSB = 1 ms
