39 / 66 page  FEDL9092-01 OKI Semiconductor ML9092-01/02/03/04 39/66 Description of the Data Section in Instructions • Key scan register (KR)—Read (for ML9092-01/04) D7 D6 D5 D4 D3 D2 D1 D0 ST2 ST1 ST0 S4 S3 S2 S1 S0 (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”. ST2 ST1 ST0 S4 S3 S2 S1 S0 0 0 0 SW04 SW03 SW02 SW01 SW00 R0 0 0 1 SW14 SW13 SW12 SW11 SW10 R1 0 1 0 SW24 SW23 SW22 SW21 SW20 R2 0 1 1 SW34 SW33 SW32 SW31 SW30 R3 1 0 0 SW44 SW43 SW42 SW41 SW40 R4 Note: SW00 to SW44 indicate the corresponding switches in Figure 1. |
