The LED Configuration register controls general LED behavior as well as the number of pulses that
are sent for the PULSE LED output behavior.
Bit 6 - RAMP_ALERT - Determines whether the device will assert the ALERT# pin when LEDs
actuated by the LED Output Control register bits have finished their respective behaviors.
‘0’ (default) - The ALERT# pin will not be asserted when LEDs actuated by the LED Output Control
register have finished their programmed behaviors.
‘1’ - The ALERT# pin will be asserted whenever any LED that is actuated by the LED Output
Control register has finished its programmed behavior.
Bits 5 - 3 - PUSLE2_CNT[2:0] - Determines the number of pules used for the Pulse 2 behavior as
shown in Table 5.49.
Bits 2 - 0 - PULSE1_CNT[2:0] - Determines the number of pulses used for the Pulse 1 behavior as
shown in Table 5.49.
