Channel 1 overcurrent threshold set to Ilim = (∆I(LDA), max · n · k), n from 0 to 255 0xFF Channel 1 overcurrent threshold set to the maximum current Table 18: Overcurrent threshold configuration channel 1 ILIM2 Addr. 0x16; bit 7:0 R/W 0xFF 0x00 Channel 2 overcurrent threshold set to the minimum current in APC mode (EACC2 = 0) or overcurrent protection disabled in ACC mode (EACC2 = 1) . . . Channel 2 overcurrent threshold set to Ilim = (∆I(LDA), max · n · k), n from 0 to 255 0xFF Channel 2 overcurrent threshold set to the maximum current Table 19: Overcurrent threshold configuration channel 2 An overcurrent event can be simulated using SOVCx. If SOVCx = 1, the corresponding overcurrent error bit OVCx will be set to 1, the error will be signaled at NCHK and the corresponding laser channel will be dis- abled. The overcurrent error will remain forced until SOVCx = 0. SOVC1 Addr. 0x1D; bit 5 R/W 0 0 No Overcurrent event at channel 1 is simulated 1 Overcurrent event at channel 1 simulated Table 20: Simulate overcurrent channel 1 SOVC2 Addr. 0x1D; bit 6 R/W 0 0 No overcurrent event at channel 2 is simulated 1 Overcurrent event at channel 2 simulated Table 21: Simulate overcurrent channel 2 |
