Description
Enable the Touch screen from low power mode.
Request a start of the ADC Reading Sequencer for Touch
screen readings.

0x0
Just like the ADSTOP above, but for the Touchscreen read
programming. This will allow independent code for ADC
Sequence readings and touchscreen ADC Sequence
readings.

Description
This will allow delay before the ADC readings.
This will allow delay between each of ADC readings in a set.
This will allow delay after the set of ADC readings. This delay
is only valid between subsequent wrap around reading
sequences with ADCONT
TSDLY1[3:0]
15-12
R/W
DIGRESETB
0x0
This will allow delay before the ADC Touch screen readings.
This is like the ADDLY1, but allows independent
programming of touchscreen readings from general purpose
ADC readings to prevent code replacement in the system.
TSDLY2[3:0]
19-16
R/W
DIGRESETB
0x0
This will allow delay between each of ADC Touch screen
readings in a set. This is like the ADDLY2, but allows
independent programming of touchscreen readings from
general purpose ADC readings to prevent code replacement
in the system.
TSDLY3[3:0]
23-20
R/W
DIGRESETB
0x0
This will allow delay after the set of ADC Touch screen
readings. This delay is only valid between subsequent wrap
around reading sequences with TSCONT mode. This is like
the ADDLY3, but allows independent programming of
touchscreen readings from general purpose ADC readings
to prevent code replacement in the system.
