[7:6] PenStrength[1:0]

Pen detect strength threshold

‘00’ – least sensitive (50 K pull-up)

‘01’ – sensitive (40 K pull-up)

‘10’ – more sensitive (30 K pull-up) - Default

‘11’ – most sensitive (20 K pull-up)

[5:3] TDetDly[2:0]

Touch detect delay

‘000’ = 40 µs

‘001’ = 80 µs

‘010’ = 160 µs

‘011’ = 320 µs

‘100’ = 640 µs - Default

‘101’ = 1.28 ms

‘110’ = 2.56 ms

‘111’ = 5.12 ms

[2:0] Settling[2:0]

Panel driver settling time

‘000’ = 40 µs

‘001’ = 80 µs

‘010’ = 160 µs

‘011’ = 320 µs/ns

‘100’ = 640 µs - Default

‘101’ = 1.28 ms

‘110’ = 2.56 ms

‘111’ = 5.12 ms

For large panels (> 6 inches), a capacitor of 10 nF is recommended at the touchscreen

terminals for noise filtering. In this case, settling time of 1 ms or more is recommended.
