A/D Accuracy
The XA-S3 A/D in 10 -bit mode is specified with 16 samples
averaged in order to factor out on-chip noise. In an application
where averaging 16 samples is not practical, the accuracy
specifications may be de-rated according to the number of samples
that are actually taken. The graph in Figure 5 shows the relationship
of additional A/D error to the number of samples that are averaged.
For example, if a single A/D reading is used with no averaging, the
A/D accuracy should be de-rated by
±
1.25 LSB.

C Rate Control, with CR1 and CR0. See text and table.
Enable I
2
C port. When ENA = 1, the I
2
C port is enabled.
Start flag. Setting STA to 1 causes the I
2
C interface to attempt to gain mastership of the bus by
generating a Start condition.
Stop flag. Setting STO to 1 causes the I
2
C interface to attempt to generate a Stop condition.
Serial Interrupt. SI is set by the I
2
C hardware when a new I
2
C state is entered, indicating that
software needs to respond. SI causes an I
2
C interrupt if enabled and of sufficient priority.
Assert Acknowledge. Setting AA to 1 causes the I
2
C hardware to automatically generate
acknowledge pulses for various conditions (see text).
