Each status signal is ANDed with its corresponding
enable signal. The enabled status signals run to a com-
mon OR gate:

LED Control Logic
The output from the OR gate is run through a pulse
stretcher, which consists of a 3-bit shift register clocked
at 38 Hz. The data input of the shift register is at logic 0.
The OR gate output asynchronously sets all three bits of
the shift register when its output goes active. The output
of the shift register controls the associated
LEDx
pin.
Thus, the pulse stretcher provides an LED output of
52 ms to 78 ms.
