Extension Driver LSI Interface
By bringing the EXT pin high, segment driver pins (SEG37 to SEG40) functions as the extended driver
interface outputs. From these pins, a latch pulse (CL1), a shift clock (CL2), data (D), and an AC signal
(M) are output. The same data is output from the SEG36 pin of the HD66710 and the start segment pin
(Seg1) of the extension driver. Due to the character baundary, the Seg1 output is used for the 5-dot font
width. For the 6-dot font width, the SEG36 output is used, and the Seg1 output of the extension driver
must not be used. When the extension driver LSI interface is used, ground level (GND) must be higher
than the V5 level.
