7. CTP Function Characteristics

7.1 I 2 C Communication

CTP provides standard I 2 C interface for communication. In the system, CTP always works in slave

mode, all communications are initiated by master, and the baud rate can be up to 400Kbps. The

definition of I 2 C timing is as following:

SCL setup time for start condition

SCL setup time for stop condition

SCL hold time for start condition

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:

7.2 Power on diagram:

Timing of setting slave address to 0x28/0x29:

Document Name:LMT070DICFWD-NSD-2-Manual-Rev0.1.docx

LCD Module User Manual

Timing of setting slave address to 0xBA/0xBB:

7.3 Data Transmission

(ex: slave address is 0xBA/0xBB)

Communication is always initiated by master, A high-to-low transition of SDA with SCL high is a start

All addressing signal are serially transmitted to and from on bus in 8-bit word. CTP sends a“0” to

acknowledge when the addressing word is 0xBA/BB (or 0x28/0x29 ). This happens during the ninth

clock cycle. If the slave address is not matched, CTP will stay in idle state.

The data words are serially transmitted to and from in 9-bit formation: 8-bit data + 1-bit ACK or NACK

sent by CTP. Data changes during SCL low periods & keeps valid during SCL high.

A low-to-high transition of SDA with SCL high is a stop condition.

Please check the above figure, master start the communication first, and then sends device address

0XBA preparing for a write operation.

After receiving ACK from CTP, master sends out 16-bit register address, and then the data word in 8-bit,

which is going to be wrote into CTP.

The address pointer of CTP will automatically increase one after one byte writing, so master can

sequentially write in one operation. When operation finished, master stop the communication.

(ex: slave address is 0xBA/0xBB)

Please check the above figure, master start the communication first, and then sends device address

0xBA for a write operation.

After receiving ACK from CTP, master sends out 16-bit register address, to set the address pointer of

LCD Module User Manual

CTP. After receiving ACK, master produce start signal once again & send device address 0xBB , then

read data word from CTP in 8-bit.

CTP also supports sequential read operation, and the default setting is sequential read mode.

Master shall send out ACK after every byte reading successfully but NACK after the last one.

Then sends stop signal to finish the communication.
