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
CSR8635 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 Section 12 for typical connections.
8.3 LED Drivers
CSR8635 QFN includes a 3-pad synchronised PWM LED driver for driving RGB LEDs for producing a wide range of
colours. All LEDs are controlled by firmware.
