Touch Screen Conversion Initiated by the Host
The time needed to convert any single coordinate either X or Y under host-controlled mode (not including the time
needed to send the command over the SPI bus) is given by:

n1 = 6 ; if conv = 8 MHz
7 ; if conv ≠ 8 MHz
n2 = 2 ; if tPVS = 0 s
0 ; if tPVS ≠ 0 s
