Description

ETRIG [1:2] – These are the external trigger inputs to the
QADC64E_A module. ETRIG1 can be configured to be
used by both QADC64E_A . Likewise, ETRIG2 can be
used by QADC64E_A. The trigger input signals are
associated with the scan queues.
PCS[6:7] – This signals provide QSPI peripheral chip
select when the enhanced PCS mode is selected.
Analog Channel 0 – Internally multiplexed input-only
analog channel. Passed on as a separate signal to the
QADC64E.
Multiplexed Analog Input (A_ANw) – Externally multiplexed
analog input.
Port A_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 (A_ANx) – Externally multiplexed
analog input.
Port A_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 (A_ANy) – Externally multiplexed
analog input.
Port A_PQB2 –This is a bidirectional general-purpose I/O
if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
Analog Input 3 – Internally multiplexed input-only analog
channel. The input is passed on as a separate signal to the
QADC64E.
Multiplexed Analog Input (A_ANz) – Externally multiplexed
analog input.
Port A_PQB 3 – This is a bidirectional general-purpose I/O
if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
Analog Input [48:51] – Analog input channel. The input is
passed on as a separate signal to the QADC64E.
Port A_PQB [4:7] – This is a bidirectional general-purpose
I/O if the QADC64E is configured in enhanced mode,
otherwise it is an input only.
