Programming Notes
1. The A/D converted data can be accessed by means of interrupt or polling method. With interrupt method,
the overall conversion time - from A/D converter start to converted data read - may be delayed because of
the return time of interrupt service routine and data access time. With polling method, to determine the read
time for TSDATXn or TSDATYn register, check the TSADCCONn[15]
−
end of conversion flag
−
bit.
2. A/D conversion can be activated in different way. After TSADCCONn[1] - A/D conversion start-by-read mode-
is set to 1. A/D conversion starts simultaneously when converted data is read.

3. If INT_PEN interrupt is used as an wakeup source in IDLE, DIDLE, STOP and DSTOP mode, XY_PST bit
(TSCONn[1:0]) should be set to waiting for interrupt mode (2b'11). UD_SEN bit (TSCONn[8]) determines a
stylus pen up wakeup or pen down wakeup.
