Non-Touch Screen Measurement Operation
The time needed to make temperature, auxiliary, or battery measurements is given by:
t + NAVG NBITS ) 1
8MHz
conv
) n1 ) n2 ) 1
tOSC ) 15 tOSC ) n3 tOSC
where:
n1 = 6 ; if conv = 8 MHz
7 ; if conv ≠ 8 MHz
n2 = 24 ; if measurement is for TEMP1 case
12 ; if measurement is for other than TEMP1 case
400 ns; if measurement is for the external/internal resistance using AUX1/AUX2
n3 = 0 ; if external reference mode is selected
3 ; if tREF = 0 s or reference is programmed for power up all the time.
1 + tREF /125 ns; if tREF ≠ 0 s and reference needs to power down between conversions.
tREF is the reference power up delay time.
