the cursor position will increase after the MRCR command is write.
Touch Panel Enable Bit
1 : Enable.
0 : Disable.
TP Sample Time Adjusting
000 : Wait 50µs for ADC data ready.
001 : Wait 100µs for ADC data ready.
010 : Wait 200µs for ADC data ready.
011 : Wait 400µs for ADC data ready.
100 : Wait 800µs for ADC data ready.
101 : Wait 1.6ms for ADC data ready.
110 : Wait 3.2ms for ADC data ready.
111 : Wait 6.4ms for ADC data ready.
Note: When touch panel detects the Touch event, to avoid the signal
instability, the sampled time is delayed to wait the signal stable. The
TP Sample Time Adjusting and ADC Clock Convert Speed relation
just refer to Section 6-4-3.
Touch Panel Wake-up Enable:
1 : Touch panel can wake-up the Sleep mode(At the condition that
0 : Disable the touch panel wake-up function
