  • Page 18: Register Detail

    3.2 Register Detail Note: Some data formats are given as (S/U # of integer bits. # of fractional bits). For example, S1.3 means the value can be either positive or negative with the first bit indicating the sign, one integer bit and three fractional bits. U0.8 means no sign bit (positive number), zero integer bits and eight fractional bits.
  • Page 19 STRBM : Strobe Mode. These bits control the functionality of the Strobe output to the illumination system. STRBM[1:0] = 00 : Active high (Activated by trigger). STRBM[1:0] = 01 : Active Low (Activated by trigger). STRBM[1:0] = 10 : Always high (Not activated by trigger). STRBM[1:0] = 11 : Always low (Not activated by trigger).
  • Page 20 Address : 0x408 (TRGDLY) Data format : U16 Default Value: 00h TRGDLY(15:8) TRGDLY(7:0) TRGDLY : This 16 bit Value is used to program a delay from the time trigger is received to when strobe is activated. A delay between 0 and 1.37s in 20.83us steps can be achieved.
  • Page 21 Address : 0x410 (RTGDLY) Data format : U16 Default Value: 00h RTGDLY(15:8) RTGDLY(7:0) RTGDLY : This 16 bit Value is used to program the delay between video frames in continues trigger Mode. A delay between 0 and 341ms in 5.21us steps can be achieved. The default value is 0.
