The time for a complete X/Y/Z1/Z2 coordinate conversion is given by(not including the time needed to send the command
over the SPI bus):
tcoordinate + 3
tPRE ) tSNS ) tPVS
125 ns
tOSC ) 4
NAVG NBITS ) 1
8MHz
conv
) n1 ) 12 ) 1
tOSC ) 33 tOSC ) n2 tOSC ) n3 tOSC
n1 = 6 ; if conv = 8 MHz
7 ; if conv ≠ 8 MHz
n2 = 4 ; if tPVS = 0 s
0 ; if tPVS ≠ 0 s
n3 = 0 ; if tSNS = 32 s
3 ; if tSNS ≠ 32 s
NOTE: The above formula is exactly valid only when the codec is powered down. Also after touch detect the formula holds true from second
conversion onwards.

NOTE: If the PINTDAV signal is programmed to be used for pen-interrupt by setting bits D15D14 of REG01H/Page2 to either 00, 01, or 11, then
the high duration of PINTDAV is given by:
