6.3
All Keys (0xC1)
Returns a 2-byte bit-field report indicating the detection status of all 11 keys.
KEY_n: 0 = key n out of detect, 1 = key n in detect (where n is 0–10).
6.4
Device Status (0xC2)
This command returns a 1-byte bit-field report indicating the overall status of the QT1110.
Bits 7 is always 1; the other bits are as follows:
DETECT: 0 = no key in detect, 1 = at least 1 key in detect.
CYCLE: 0 = cycle time is good, 1 = cycle time over-run. A cycle time over-run occurs when it
takes longer to measure and process all the keys than the assigned cycle time.
ERROR: 0 = no key in error state, 1 = at least 1 key in error.
CHANGE: 0 = CHANGE pin is asserted, 1 = CHANGE pin is floating.
EEPROM: 0 = EEPROM is good, 1 = EEPROM has an error. If there are no settings stored in
EEPROM, the EEPROM error bit is set and a zero EEPROM CRC is returned.
RESET: set to 1 after power-on or reset, cleared when “Device Status” is read.
GUARD: 0 = guard channel is not in detect, 1 = guard channel is active or in detect. This bit will
be zero if the guard channel is not enabled.
6.5
EEPROM CRC (0xC3)
This command returns a 1-byte CRC checksum for the setup data in EEPROM.
6.6
RAM CRC (0xC4)
This command returns a 1-byte CRC checksum for the setup data in RAM.
