Touch Report Protocol
Touch coordinates, when available, are provided to the
master by the AR1021 in the following protocol (See
FIGURE 4-3:
I2C TOUCH REPORT PROTOCOL
Note that the IRQ signal shown above occurs on the
SDO pin of the AR1021.
4.9
Command Protocol
The master issues supported commands to the
AR1021 in the following protocol.
Below is an example of the ENABLE_TOUCH command

I2C COMMAND PROTOCOL
Note that the IRQ shown above occurs on the SDO pin.
0x9A
AR1021 Device ID address
0x00
Protocol command byte (send 0x00 for
the protocol command register)
0x55
Header
0x01
Data size
0x12
Command
4.10
Sleep State
Pending communications are not maintained through a
sleep/wake cycle.
If the SDO pin is asserted for a pending touch report or
command response, and the AR1021 enters a Sleep
state, prior to the master performing a read on the data,
then the data is lost.
