Figure 40-4. Touch Screen Pen Detect
The Touch Screen Pen Detect can be used to generate a TSADCC interrupt to wake up the sys-
tem or it can be programmed to trig a conversion, so that a position can be measured as soon as
a contact is detected if the TSADCC is programmed for an operating mode involving the Touch
Screen.
The Pen Detect generates two types of status, reported in the
Both bits are automatically cleared as soon as the Status Register TSADCC_SR is read, and
can generate an interrupt by writing accordingly the
• the bit PENCNT is set as soon as a current flows for a time over the debouncing time as
• the bit NOCNT is set as soon as no current flows for a time over the debouncing time as
defined by PENDBC and remains set until TSADCC_SR is read.
