Operational Description

• Display data input

As shown in the section on data configuration, the data for display consists of a data field

corresponding to segments ON/OFF and a command field indicating display data input.

The C0 bit of the command field is set to "0" (common A) or "1" (common B) according to the

common corresponding to the display data. LED display data corresponds to common A.

Data input to the DATA I/O pin is captured by a shift register at rising edge of a clock signal,

then is transferred to a data latch for display when the LOAD signal is at "H" level, and is

output through a segment driver.

Old Data

New Data

The status of a key switch is indicated by ON = 1, OFF = 0, and is read as 30-bit serial data.

(For information on the sequence, see the section on data configuration.) To output data, first

write the "Key Data Output" command, then apply a clock signal. Data is then output

synchronizing with the rising edge of the clock signal. After that, when a LOAD pulse is

added, the DATA I/O pin returns to the input state, and the next data or command can be

input.
