Note:
See the relevant software release note for the implementation of these PIO lines, as they are firmware build-
specific.
8.2 Analogue I/O Ports, AIO
CSR8615 QFN has 1 general-purpose analogue interface pin, AIO[0]. Typically, this connects to a thermistor for
battery pack temperature measurements during charge control. See for typical connections.
