KEY1 KEY2 The data of each key is stored as follows, and is read with the read command starting from the least significant bit. KEY1 KEY2 KEY1 KEY2 KEY1 KEY2 KEY1 KEY2 Seg1/KS1 Seg2/KS2 Seg3/KS3 Seg4/KS4 Seg5/KS5 Seg6/KS6 Seg7/KS7 Seg8/KS8 Seg9/KS9 Seg10/KS10 Seg11/KS11 Seg12/KS12 Reading Sequence Seg13/KS13 Seg14/KS14 Seg15/KS15 Seg16/KS16 b0 b1 b2 b3 b4 b5 b6 b7 5.1 LED Port Data is written to the LED port with the write command, starting from the least significant bit. “L” output when the bit of this port is 0, and “H” output when the bit is 1. The data of bits after the 5th bit are ignored. MSB LSB b3 b2 b1 b0 −− − − Don't care LED1 LED2 LED3 LED4 Remark Power ON application, all the LED ports are “L” output. |
