REFERENCE MANUAL
If the CCW channel field specifies a reserved channel number (channels 32 to 47) or
an invalid channel number (channels 4 to 31 in the non-multiplexed mode), the low ref-
erence level (V
RL
) is converted. The channel field is programmed for channel 63 to in-
dicate the end of the queue. Channels 60 to 63 are special internal channels. When
one of the special channels is selected, the sampling amplifier is not used. The value
of V
RL
, V
RH
, or V
DDA
/2 is placed directly onto the converter. Also for the internal spe-
cial channels, programming any input sample time other than two has no benefit ex-
cept to lengthen the overall conversion time.
7.8 Result Word Table
The result word table is a RAM, 40 words long and 10 bits wide. An entry is written by
the QADC after completing an analog conversion specified by the corresponding CCW
table entry. Software can read or write the result word table, but in normal operation,
the software reads the result word table to obtain analog conversions from the QADC.
Unimplemented bits are read as zeros, and write operations do not have any effect.
While there is only one result word table, the data can be accessed in three different
data formats:
Right justified in the 16-bit word, with zeros in the higher order unused bits.
Left justified, with the most significant bit inverted to form a sign bit, and zeros in
the unused lower order bits.
Left justified, with zeros in the lower order unused bits.
