The switching of the three LED NMOS switches (P, Q, and R) is controlled such that a switch is returned to the OPEN position first before the subsequent switch is set to the CLOSED position (BBM). (See Figure 9.) The dead time between opening and closing switches is controlled through the BBM register (0x0E). Switches that already are in the CLOSED position and are to remain in the CLOSED state are not opened during the BBM delay time.
