10.3.3 Comparator event
The comparator can generate a wake-up interrupt when a change in the relative levels of
the positive and negative inputs occurs. The ability to wake up when continuously
monitoring analog signals is useful in ultra-low power applications. For example, the
JN517x can remain in sleep mode until the voltage drops below a threshold and then be
woken up to deal with the alarm condition; the comparator has a low current mode to
facilitate this.
10.3.4 Pulse counter
The JN517x contains two 16-bit pulse counters that can be programmed to generate a
wake-up event. Following the wake-up event the counters will continue to operate and
therefore no pulse will be missed during the wake-up process. These counters are
described in Section 9.11.To minimize sleep current it is possible to disable the 32 kHz RC
oscillator and still use the pulse counters to cause a wake-up event, provided debounce
mode is not required.
10.4 Deep sleep mode
Deep sleep mode gives the lowest power consumption. All switchable power domains are
off and most functions in the V_DD supply power domain are stopped, including the 32 kHz
RC oscillator. However, the Brown-Out Reset remains active as well as all the DIO cells.
This mode can be exited by a hardware reset on the RESET_N pin, or an enabled DIO
wake-up event.
10.5 Flicker control
FLICK_CTRL feature is dedicated to lighting application in a bulb. It allows either to do a
OR or NOR function from RFRX and RFTX to be outputted on one of DIO. Aim of this
feature is to compensate the variation of current of the IC depending of the mode (RX/TX)
when using Lighting application.
