VFD CONTROLLER/DRIVER
DESCRIPTION
Fluorescent Display) controller/driver that is driven on a 1/8- to 1/16
duty factor. It consists of 12 segment output lines, 8 grid output lines, 8
segment/grid output drive lines, a display memory, a control circuit, and
a key scan circuit. Serial data is input to the SC16311 through a three-
line serial interface. This FIP controller/driver is ideal as a peripheral
device of a single-chip microcomputer.

... FUNCTION DESCRIPTION Display RAM Address and Display Mode The display RAM stores the data transmitted from an external device to theSC16311 through the serial interface, and is assigned addresses as follows, in units of 8 bits: Seg1 Seg4 Seg8 00HL 00HU 03HL 03HU 06HL 06HU 09HL 09HU ...

... Command A command sets the display mode and status of the FIP driver. The first 1 byte input to theSC16311 through the DIN pin after the STB pin has fallen is regarded as a command. If STB is made high while a command/data is transmitted, serial communication is initialized, and the command/data being transmitted is invalid (however, the command/data already transmitted remains valid). ...
