5.8.2 Quadrature Decoder

The following feature exists in hardware but cannot be configured in the firmware currently:
The quadrature decoder provides buffered decoding of quadrature-encoded sensor signals. It is suitable

for mechanical and optical sensors with an optional LED output signal and input debounce filters. The
sample period and accumulation are configurable to match application requirements. All pins
individually can be configured to carry quadrature demodulator signals.

5.8.3 ADC

The ADC is an alternate function on SIO pins, configurable by
The BL600 provides access to six-channel 10-bit incremental ADC. This enables sampling up to six external
signals through a front end MUX. The ADC has configurable input and reference prescaling and sample
resolution (8, 9, and 10 bit).
smart
Note: Current BASIC runtime engine firmware (since v1.1.50.0) provides access to 10-bit mode
resolution only.

5.8.4 PWM and FREQ signal output on up to 2 SIO pins
The PWM and FREQ output is an alternate function on SIO pins, configurable by
The ability to output a PWM (Pulse Width Modulated) signal or FREQ output signal on up to 2 GPIO (SIO)
output pins has been added since
GpioSetFunc() function.
PWM output signal has a frequency and duty cycle property. PWM output is generated using 32-bit hardware
timers. The timers are clocked by a 1MHz clock source. Frequency is adjustable (up to 1 MHz ) and the Duty
cycle can be set over range from 0% to 100% (both configurable by
frequency driving each of the 2 SIO pins is the same but the duty cycle can be independently set for each pin.
FREQ output signal frequency can be set over a range of 0Hz to 4MHz (with 50% mark-space ratio).
