Queued Analog-to-Digital Converter (QADC)

V
reference inputs from the power supply signals allows for additional external filtering, which increases
reference voltage precision and stability, and subsequently contributes to a higher degree of conversion
accuracy.

The V
power is required to isolate the sensitive analog circuitry from the normal levels of noise present on the
digital power supply.

The QADC occupies 1 Kbyte, or 512 half-word (16-bit) entries, of address space. Ten half-word registers
are control, port, and status registers, 64 half-word entries are the CCW table, and 64 half-word entries are
the result table which occupies 192 half-word address locations because the result data is readable in three
data alignment formats.
