Description
1
Analog Input [52:54] – Input-only. These inputs are passed
on as separate signals to the QADC64E.
Multiplexed Address [0:2] for QADC64E Module A–
Output. Provides a three-bit multiplexed address output to
the external multiplexer chip to allow selection of one of the
eight inputs.
Port A_PQA [0:2] – This is a bidirectional general-purpose
I/O.
Analog Input [55:59] – Input-only. These inputs are passed
on as separate signals to the QADC64E.
Port A_PQA [3:7] – This is a bidirectional general-purpose
I/O.
Analog Channel 0 – Internally multiplexed input-only
analog channel. Passed on as a separate signal to the
QADC64E.
Multiplexed Analog Input (B_ANw) – Externally multiplexed
analog input.
Port B_PQB0 – This is a bidirectional general-purpose I/O
if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
Analog Channel 1 – Internally multiplexed input-only
analog channel. Passed on as a separate signal to the
QADC64E.
Multiplexed Analog Input (B_ANx) – Externally multiplexed
analog input.
Port B_PQB1 –This is a bidirectional general-purpose I/O
if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
Analog Channel 2 – Internally multiplexed input-only
analog channel. The input is passed on as a separate
signal to the QADC64E.
Multiplexed Analog Input (B_ANy) – Externally multiplexed
analog input.
Port B_PQB2 –This is a bidirectional general-purpose I/O
if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
