Notes
● Controls ​ M aximum Aquisition Count
● Default Value:​ 0x80
Range:​ 0x00­0xFF (0­255).
●
● Control the FPGA maximum signal integration time.
● Stronger signal results in reduced acquisition count to prevent internal register overflow.
● Sig overflow flag and Ref overflow flag in control register 1 are set when automatic limiting occurs.
Control Register #3(0x03) (control_reg [3]:)
Bit
Bits 7­4 Stop address (default 5 corresponding to 512)
Bits 3­0 Start address (default 1 corresponding to 64)
Notes
● control_reg[0x51]:​ Correlation start and stop locations used for signal acquisition (write only)
Start address:​ Value in the range from 0x00­0x0f – starting point in correlation record (record
●
broken into 64 element segments 1024 total
Stop address:​ Value in the range from 0x00­0x0f – stopping point in correlation record
●
● With longer correlation records, burst pulse period is roughly proportional to the length of the
correlation record. Unnecessarily long record length increases the probability of false detection
Control Register #4 (0x04) – Mode Control (control_reg[4]:)
