DETAILED REGISTER DESCRIPTIONS
All addresses and default values are expressed in hexadecimal.
Table 12. Control Register 1
Address
Bit Name
Data Bit
Description
Default
Value
0x01
Disable PENIRQ
15
Pen interrupt enable.
0x0000
0 = PENIRQ is enabled.
1 = PENIRQ is disabled and INT is enabled.
CHNL ADD[2:0]
[14:12]
ADC channel address for manual conversion (ADC mode = 01).
111 = X+ input (Y position).
110 = Y+ input (X position).
101 = X+ (Z1) input for touch-pressure calculation.
100 = Y (Z2) input (used for touch-pressure measurement).
011 = AUX input.1
010 = VBAT input.1
001 = temperature measurement.
000 = not applicable.
ADC MODE[1:0]
[11:10]
ADC mode.
00 = no conversion.
01 = single conversion.2
10 = conversion sequence (slave mode).2
11 = conversion sequence (master mode).
ACQ[1:0]
[9:8]
ADC acquisition time.
00 = 4 clock periods (2 s).
01 = 8 clock periods (4 s).
10 = 16 clock periods (8 s).
11 = 32 clock periods (16 s).
Note that the acquisition time does not apply to the temperature sensor channels;
the temperature channel has a constant settling time of 16 μs.
TMR[7:0]
[7:0]
Conversion interval timer.
Starts at 550 s (00000001) and continues to 9.440 ms (11111111) in steps of 35 s
Note that, in slave mode, the conversion interval timer starts to count as soon as the
conversion sequence is finished; in master mode, it starts to count again only if the
screen remains touched. If the screen is released, the timer stops counting and, on
the next screen touch, a conversion starts immediately.
1
If GPIO is enabled in Control Register 2 (Bit 13), AUX and VBAT are both ignored. If AUX and VBAT are both selected in Control Register 3 and GPIO is disabled, AUX is
ignored and VBAT is measured.
2
Note that these bits are cleared to 00 at the end of the conversion sequence if the conversion interval timer bits in Control Register 1 (Address 0x01) Bits[7:0] = 0x00 at
the end of the conversion sequence.
