9520J–AT42–05/2013

AKS_EN: 0 = AKS is disabled, 1 = AKS is enabled.

CAL: 0 = normal, 1 = calibrating.

KEY_EN: 0 = key is disabled, 1 = key is enabled.

6.11

Detect Output States (0xC6)

This command returns a byte that indicates which PWM signal is applied to each DETECT pin.

DET_n: 0 = “Out of Detect” PWM is output, 1 = the “In Detect” PWM is output.

Note:

Note: During “LED Detect Hold Time” or “LED Fade”, the report indicates the new state of the DETECT pin.

For example, if the DETECT output is in “LED Detect Hold Time” before switching to “Out of Detect” PWM,

the reported state is “0”.

6.12

Last Command (0xC7)

This command returns the previous 1-byte command that was received from the host. Note that this command does

not return itself.

6.13

Setups (0xC8)

This command returns the 42 bytes of the setups table, starting with address 0, with the most significant bit first.

6.14

Device ID (0xC9)

This command returns 1 byte containing the device ID (0x57).

6.15

Firmware Version (0xCA)

Returns 1 byte containing the firmware version.
