NAME DESCRIPTION
E5h
TOF_DIFF_
AVGInt
16-bit xed-point two’s-complement integer portion of the average of the accumulated TOF_DIFF
measurements. It is computed as:
This integer represents the number of t
4MHz
periods that contribute to the computation. The
maximum size of the integer is 7FFFh or (2
15
- 1) x t
4MHz
. The minimum size of this integer is
8000h or -2
15
x t
4MHz
.
E6h
TOF_DIFF_
AVGFrac
16-bit fractional portion of the two’s-complement average of the accumulated TOF_DIFF
measurements. This fractional portion is a binary representation of one t
4MHz
period quantized
to a 16-bit resolution. The maximum size of the fraction is FFFFh or (2
16
- 1)/2
16
x t
4MHz
.
E7h T1Int
15-bit xed-point integer value of the time taken to discharge the timing capacitor through
the RTD connected to the T1 device pin. This integer portion is a binary representation of the
number of t
4MHz
periods that contribute to the time results. The maximum size of the integer is
7FFFh or (2
15
- 1) x t
4MHz
.
E8h T1Frac
16-bit fractional value of the time taken to charge the timing capacitor through the RTD
connected to the T1 device pin. This fractional portion is a binary representation of one t
4MHz
period quantized to a 16-bit resolution. The maximum size of the fraction is FFFFh or (2
16
-
1)/2
16
x t
4MHz
.
E9h T2Int
15-bit xed-point integer value of the time taken to charge the timing capacitor through the RTD
connected to the T2 device pin. This integer portion is a binary representation of the number of
periods that contribute to the time results. The maximum size of the integer is 7FFFh or
(2
15
- 1) x t
4MHz
.
EAh T2Frac
16-bit fractional value of the time taken to charge the timing capacitor through the RTD
connected to the T2 device pin. This fractional portion is a binary representation of one t
4MHz
period quantized to a 16-bit resolution. The maximum size of the fraction is FFFFh or (2
16
-
1)/2
16
x t
4MHz
.
EBh T3Int
15-bit xed-point integer value of the time taken to charge the timing capacitor through the RTD
connected to the T3 device pin. This integer portion is a binary representation of the number of
t
4MHz
periods that contribute to the time results. The maximum size of the integer is 7FFFh or
(2
15
- 1) x t
4MHz
.
ECh T3Frac
16-bit fractional value of the time taken to charge the timing capacitor through the RTD
connected to the T3 device pin. This fractional portion is a binary representation of one t
4MHz
period quantized to a 16-bit resolution. The maximum size of the fraction is FFFFh or (2
16
-
1)/2
16
x t
4MHz
.
EDh T4Int
15-bit xed-point integer value of the time taken to charge the timing capacitor through the RTD
connected to the T4 device pin. This integer portion is a binary representation of the number of
t
4MHz
periods that contribute to the time results. The maximum size of the integer is 7FFFh or
(2
