43 / 78 page  STFPC320 Key matrix 43/78 8.1 Key read sequence Description: For example when the key corresponding to the KEY1/KS1 is pressed, the bit b0 of Byte 3 will be set. This is decoded as the key value connected to KEY1/KS1 which could be “PLAY” (for example). When the processor decodes the key value corresponding to the “PLAY” key, it takes the necessary action (e.g. play the disc). Note: Upon a key-press, the IRQ_N/SQW pin will be asserted. The interrupt flag should be read to know the source of interrupt. The interrupt flag is read by sending the 0x63 command. As soon as the interrupt buffer is read, the IRQ_N/SQW pin will be de-asserted.
