In iC-WK mode both channels operate in APC mode. The internal programmable logarithmic monitor resis- tors are disabled, therefore connection of external re- sistors at pins MDAx is required. The APC reference can be set to two different val- ues by means of pin INS/WKR, as it is explained in table 5, and the overcurrent threshold is set to its max- imum value of 750 mA (cf. Electrical Characteristics No. 107). In case of overcurrent, the respective chan- nel is disabled. For re-enabling the channel, the corre- sponding ECx pin must be set lo and then back hi. Reference Voltage in iC-WK mode INS/WKR Reference Voltage similar to Lo 0.25 V iC-WKM Hi 0.5 V iC-WK, iC-WKL, iC-WKN Table 5: Reference selection (cf. Electrical Character- istics No. 110 ) External CI capacitors must be added in this opera- tion mode at pins CIx and CILx. Figure 4 shows an example in iC-WK mode using an N-type laser diode, where 0.5 V reference is selected. Figure 5 presents the same configuration with an M-type laser diode.
