7.2 I 2 C Slave Addresses

CTP has 2 sets of slave address 0xBA/0xBB & 0x28/29. Master can control Reset & INT pin

to configure the slave address in power on initial state like following:

7.3

I 2 C Data Transmission

(For example ： device address is 0xBA/0xBB)

1. Communication is always initiated by the host. Valid Start condition is signaled by pulling SDA linefrom

“high” to “low” when SCL line is “high”. Data flow or address is transmitted after the Startcondition.

2. All slave devices connected to I2C bus should detect the 8-bit address issued after Start condition and

send the correct ACK. After receiving matching address, GT911 acknowledges by configuring SDA

line as output port and pulling SDA line low during the ninth SCL cycle. When receiving

unmatchedaddress, namely, not 0XBA or 0XBB, GT911 will stay in an idle state.

3. For data bytes on SDA, each of 9 serial bits will be sent on nine SCL cycles. Each data byte consists.of 8

valid data bits and one ACK or NACK bit sent by the recipient. The data transmission is valid when SCL

line is “high”.

4. When communication is completed, the host will issue the STOP condition. Stop condition implies

the.transition of SDA line from “low” to “high” when SCL line is “high”.

CTP I 2 C Data Write

(For example ： device address is 0xBA/0xBB)

1. The diagram above displays the timing sequence of the host writing data onto GT911. First, the host

issues a Start condition. Then, the host sends 0XBA (address bits and R/W bit; R/W bit as 0 indicates

Write operation) to the slave device.

2. After receiving ACK, the host sends the 16-bit register address (where writing starts) and the 8-bit

data bytes (to be written onto the register).

3. The location of the register address pointer will automatically add 1 after every Write Operation.

Therefore, when the host needs to perform Write Operations on a group of registers of continuous

addresses, it is able to write continuously. The Write Operation is terminated when the host issues the

Stop condition.

CTP I 2 C Data Read

(For example ： device address is 0xBA/0xBB)

1 . The diagram above is the timing sequence of the host reading data from GT911. First, the host issues.a

Start condition and sends 0XBA (address bits and R/W bit; R/W bit as 0 indicates Write operation)

to the slave device.

2. After receiving ACK, the host sends the 16-bit register address (where reading starts) to the slave

device. Then the host sets register addresses which need to be read.

3. Also after receiving ACK, the host issues the Start condition once again and sends 0XBB (Read

Operation). After receiving ACK, the host starts to read data.

4. GT911 also supports continuous Read Operation and, by default, reads data continuously.

Whenever.receiving a byte of data, the host sends an ACK signal indicating successful reception. After

receiving.the last byte of data, the host sends a NACK signal followed by a STOP condition which

terminates communication.
