to X and Y data registers. Scan continues until either the pen is lifted or a stop bit is
sent.
0010 => Touch screen scan function: X, Y, Z1 and Z2 coordinates are converted and the results
returned to X, Y, Z1 and Z2 data registers. Scan continues until either the pen is lifted
or a stop bit is sent.
0011 => Touch screen scan function: X coordinate is converted and the results returned to X data
register.
0100 => Touch screen scan function: Y coordinate is converted and the results returned to Y data
register.
0101 => Touch screen scan function: Z1 and Z2 coordinates are converted and the results
returned to Z1 and Z2 data registers
0110 => BAT input is converted and the results returned to the BAT data register.
0111 => AUX2 input is converted and the results returned to the AUX2 data register
1000 => AUX1 input is converted and the results returned to the AUX1 data register.
1001 => Auto Scan function: For AUX1, AUX2, TEMP1 or TEMP2 as chosen using control
register 0CH/page 1. Scan continues until stop bit is sent or D13D10 are changed.
1010 => TEMP1 input is converted and the results returned to the TEMP1 data register.
1011 => Port scan function: BAT, AUX1, AUX2 inputs are measured and the results returned to
the appropriate data registers.
1100 => TEMP2 input is converted and the results returned to the TEMP2 data register.
