b) When jumper J2 is bridged,

Note: 5V voltage for the LED backlight should be supplied to Pin19 (LEDA) and Pin20
(LEDK) terminal of the interface, it should not be supplied to the Anode/Cathode terminal
of the LED backlight directly.
4. MPU INTERFACE
4.1 Selection of Interface Type
The SED1520 uses 8 bits bi-directional data bus (DB0–DB7) to transfer data. The /RST
terminal is capable of selecting MPU interface: setting the level of /RST to either “H” or “L”
can provide direct interface of the SED1520 with a 68 or 80 series MPU.
With /CS at high level, the SED1520 is independent from the MPU bus and stays in
standby mode. In this mode, however, the reset signal is input independently of the
internal status.
