TSC2004: Questions about the PSM bit of Configuration Register 0

Hiroaki,

The answers to your question are below in red.

Q1:
Please tell me the delay time from when touch-on is detected until the PSM bit is set to 1.  PSM will be set one clock cycle after on-touch is detected.  About 300ns

Q2:
On the operation of the PSM bit during the Detecting Touch period after Preprocessing for Y Coordinate,
will the PSM bit be cleared to 0 during screen capacity precharge operation?  No. PSM is not cleared by this operation.  PSM will be cleared when off-touch occurs.
(Please refer to attached figure 40.)

Q3:
When touch-off occurs at the timing shown in Figure 40, will not the Z1 Coordinate and Z2 Coordinate process be executed?  If off-touch occurs, as you show in the figure, the Z coordinate process will not be executed and the X and Y data will not be updated. The X and Y data will contain the old values.
After that, will the latest conversion data be read out for X-Data and Y-Data?  No. The X and Y data will contain the old values.
(Please refer to attached figure 40.)
