16. SELF-DIAGNOSIS FUNCTION
This function checks whether the timing of each column driver is different from that of the others due to external
noise. A slave chip compares internally generated L1 and L2 with L1 and L2 of the master chip. If a discrepancy is
found, a refresh signal is transmitted to all column drivers. On reception of the refresh signal, internal reset is
effected, and timing is initialized. At this time, the display is turned OFF while /REFRH = L for 4 frame cycles.
Discrepancy between L1 and L2 is monitored at the rising edge of /FRM once in 1/2 frame.
