PenStateReportDelay Register

(OFFSET 0x0F)

The PenStateReportDelay register sets the delay time

between sending of sequential touch reports for the

“Pen-Down” and “Pen-Up” Touch mode states. See

Section 8.2.10 “TouchMode Register (offset 0x0C)”

for touch modes.

For example, if “Pen-Up” state of the TouchMode

followed by a touch report with P=0, then this delay

occurs between the two touch reports. This provides

some timing flexibility between the two touch reports

that may be desired in certain applications. Valid values

are as follows.

0 ≤ PenStateReportDelay ≤ 255

Pen State Report Delay Time = PenStateReportDelay *

50 μs

8.2.14

TouchReportDelay Register (OFFSET

0x11)

The TouchReportDelay register sets a forced delay

time between successive touch report packets. This

allows slowing down of the touch report rate, if desir-

able for a given application. For example, a given appli-

cation may not need a high rate of touch reports and

may want to reduce the overhead used to service all of

the touch reports being sent. In this situation, increas-

ing the value of this register will reduce the rate at

which the controller sends touch reports. Valid values

are as follows:

0 ≤ TouchReportDelay ≤ 255

Touch Report Delay Time ≈ TouchReportDelay * 500 μs
