... TB62709N/F TB62709N/F Data Decode The TB62709F utilizes two basic modes of operation. In the DECODE MODE, data encoded in data bits D7~D0 is decoded to display preset characters per table 8. This mode is activated as illustrated in table 5. With D15~D8 programmed as 21 Hex and D7~ Hex the DECODE MODE is selected. ...

... TB62709N/F TB62709N/F TB62709N/F TB62709N/F TB62709N/F Brightness Control Brightness is controlled by controlling the “on time” duty cycle. The device allows for 16 bright- ness steps as illustrated in list 3 with 0/16 as the dimmest setting (not illuminated) to 15/16 as the brightest setting. The duty cycle control register is addressed with a 20 Hex command at D15~D8 and the appropriate data per list 3 at D3~D0 ...

The characters are initially set at full brightness (15/16 duty cycle) and displayed. The duty cycle is then changed to half brightness (8/16 duty cycle) as the display is first blanked and then acti- vated with the same a,b,c and d characters ...
