Description of the Data Section in Instructions
Key scan register (KR)—Read (for ML9092-01/04)

(1) D7 to D5 (ST2 to ST0) (Key scan read count display bits)
25-bit key scan data is divided into 5 groups and read. The read count is indicated by bits ST2 to ST0.
Every time key scan data is read, these bits are automatically incremented over the range of “000” to “100”. After
counting to “100”, this counter is reset to “000” and then again incremented from “000”, thereafter repeating this
cycle. If the
CS
signal is risen up during the cycle of counting, the scan read counter bits are returned to “000”.
If the
RESET
pin is pulled to a “L” level, these bits are reset to “0”.
(2) D4 to D0 (S4 to S0) (Key scan read data bits)
These bits are read as 25-bit serial data that expresses the key switch status (1 = ON, 0 = OFF). Data is divided into
5 groups and read. (For the read order, refer to the description below.) The read count is indicated by bits ST2 to
ST0.
The correspondence between the scan read count data, key scan data and key matrix switches is shown below.
If the
RESET
pin is pulled to a “L” level, these bits are reset to “0”.
