Reserved. Unknown during read.
Synchronous Data Ready. This bit is set when new
conversion data from the ADC digital filter appears the
TSXYResult register. The bit is cleared when the
TSXYResult register is read. The bit is always clear unless
the touch screen scanning state machine is disabled
(TSSetup bit 15 is zero).
X and Y controller calculated reading when touch screen
controller is enabled at 12-bit resolution. The interrupt
output is cleared when this register is read.
Direct analog-to-digital controller output when touch
screen controller is disabled at 16-bit resolution.
Reserved. Unknown during read.
Analog switch control value for direct analog switch control
only (TSDirect) when the touch screen controller is
disabled. Controls DAC routing to ADC input.
