[11:0] DATA: data bytes from TSC FIFO
The data format from the TSC_DATA register depends on the setting of "OpMode" field in
TSC_CTRL register. The samples acquired are accessed in "packed samples". The size of
each "packed sample" depends on which mode the touch screen controller is operating in.
The TSC_DATA register can be accessed in 2 modes:
●
●
To access the 128-sets buffer, the non autoincrement mode should be used.
