0x05: GT911 has finished transmitting a data frame but the transmission fails. Instead of notifying the
host via INT, GT911 will resend the data frame automatically.
Please note that, if the transmission is unsuccessful, GT911 will not stop resending until the data is transmitted
successfully. Therefore, the Send Failure status needs to be defined as “timeout setting of the host” or “Leave
Detection”.
0x07: GT911 has detected that the receiving terminal has left. After the host capturing this status, GT911 may
exit Send mode. When transmitting a data frame successfully, GT911will enable Leave detection. GT911 can
distinguish whether the receiving terminal exists or not by detecting the feedback signal on the frequency
sweep signal sequence. If no feedback signal is detected for 1s, it is regarded that the receiving terminal has
left.
[0xAB11] RevStatus
This register indicates the Receive status in Receive Mode.
0x01: indicates GT911 is in idle state. It is detecting data from the transmitting terminal but no valid
signal has been detected yet.
0x02: indicates GT911 has detected the start signal and is receiving data.
0x03: indicates GT911 has received a data frame successfully and has sent it to the Receive Buffer.
GT911 will notify the host to process the data via INT. After reading the data in Receive Buffer, the host
has to write a number other than AA to 0xAB1F.
0x04: indicates GT911 has received a data frame but does not pass the CRC16 verification. Instead of
notifying the host to handle via INT, GT911 will automatically detect the start signal again.
Please note that if the CRC verification fails or an overlong void signal is received, it will not stop
detecting the start signal until the data frame is received successfully. Therefore, Receive Failure should be
implemented by the host through timeout setting.
0x07:GT911 detected that the transmitting terminal has left. After the host capturing this status, GT911 may
exit receive mode. When receiving a data frame successfully, GT911 will start Leave detection. GT911 can
distinguish whether the transmitting terminal exists or not by detecting the frequency sweep signal sequence
sent by the transmitting terminal. If no signal is detected for 1s, it is regarded that the transmitting terminal
has left.
