16.3 CURRENT SINK INTERRUPTS

Current Sink 2
Table 50 Configuring On/Off Ramp Timing for ISINK1 and ISINK2
The Current Sinks are associated with two Interrupt event flags, which indicate if the Current Sinks
are unable to sink the demanded current (eg. if the power source is too low or if the load is open
circuit). Each of these secondary interrupts triggers a primary Current Sink Interrupt, CS_INT (see
Section 23). This can be masked by setting the mask bit(s) as described in Table 51.

11 = 1 step every 16ms (880ms)
The time quoted in brackets is valid for
the maximum change in current drive
setting. The actual time scales
according to the extent of the change in
current drive setting.
