ADAVG
00
R/W
Converter Averaging Control. These two bits allow user to specify the number of averages the
converter will perform selected by bit D0, which selects either Mean Filter or Median Filter.
Mean Filter
Median Filter
00 => No average
No average
01 => 4-data average
5-data average
10 => 8-data average
9-data average
11 => 16-data average 15-data average
D5D4
ADCR
00
R/W
Conversion Rate Control. These two bits specify the internal clock rate, which the ADC uses to
control performing a single conversion. These bits are the same whether reading or writing.
tconv +
N ) 4
INTCLK
Where fINTCLK is the internal clock frequency. For example, with 12-bit resolution and a 2 MHz
internal clock frequency, the conversion time is 8 s. This yields an effective throughput rate of
125 kHz.
00 => 8 MHz internal clock rate (use for 8-bit resolution only)
01 =>4 MHz internal clock rate (use for 8-bit/10-bit resolution only)
10 =>2 MHz internal clock rate
11 =>1 MHz internal clock rate
D3D1
PVSTC
000
R/W
Panel Voltage Stabilization Time Control. These bits allow user to specify a delay time from the
time the touch screen drivers are enabled to the time the voltage is sampled and a conversion
is started. This allows the user to adjust for the settling of the individual touch panel and external
capacitances.
000 => 0 s stabilization time
001 => 100 s stabilization time
010 => 500 s stabilization time
011 => 1 ms stabilization time
100 => 5 ms stabilization time
101 => 10 ms stabilization time
110 => 50 ms stabilization time
111 => 100 ms stabilization time

D15D14 PINTDAV
10
R/W
Pen Interrupt or Data Available. These two bits program the function of the PINTDAV pin.
00 => Acts as PEN interrupt (active low) only. When PEN touch is detected, PINTDAV goes low.
01 => Acts as data available (active low) only. The PINTDAV goes low as soon as one set of ADC
conversion(s) is completed. For scan mode, PINTDAV remains low as long as all the
appropriate registers have not been read out.
10 => Acts as both PEN interrupt and data available. When PEN touch is detected, PINTDAV goes
low. PINTDAV goes high once all the selected conversions are over.
11 => Same as 10
D13
PWRDN
0
R
TSCADC Power down status
0 => TSCADC is active
1 => TSCADC stops conversion and powers down
D12
HCTLM
0
R
Host Controlled Mode Status
0 => Host controlled mode
1 => Self (TSC2101) controlled mode
D11
DAVAIL
0
R
Data Available Status
0 => No data available.
1 => Data is available(i.e one set of conversion is done)
Note: This bit gets cleared only after all the converted data have been completely read out. This bit
is not valid in case of buffer mode.
