13 / 50 page  13 9571A–AT42–02/10 AT42QT1111-MU/AT42QT1111-AU For example, Figure 4-3 on page 12 shows the exchange that takes place to read the 2-byte “All Keys” report. In this exchange, the host sends: 0xC1 — 0x00 — 0x00 and the QT1110 returns (simultaneously): 0x55 — Report Byte 0 — Report Byte 1 If CRC is enabled, this exchange is extended to 5 bytes, as shown in Figure 4-4. Figure 4-4. All Keys Report – CRC Enabled 4.1.5.1 Set Instructions Set Instructions are 2-byte transmissions by the host that are used to send settings to individual locations in the device memory map. At the first byte, the QT1111 returns 0x55 (“Idle”) to confirm that it will interpret the byte as a new command. At the second byte, the QT1111 returns the “Set” command it has just received. For example, to set the “Positive Recalibration Delay” to 1920 ms, address 5 in the memory map is set to 12 (0x0C). This is done with the “Set” command for address 5 (command code 0x95), as shown in Figure 4-5 on page 14. Host (Sends on MOSI) Command: 0xC1 Null: 0x00 Key Status Report Byte 0 Null: 0x00 Key Status Report Byte 1 Null: 0x00 Report CRC: 0x?? Simultaneous Transmission Command CRC: 0x94 Response: 0x94 (Expected Command CRC) Response: 0x55 ( Idle” Fresh Command) “ – Device (Responds on MISO) |
