unexpected nRF24LE1 reset when going into sleepMode

[robotox]

Hi,

when executing the following code in my application. if face chip reset time to time. I've investigated code to find the bug origin and then notice that i ve a difference in my hardware design. I use a pullup resistor of 10k on the Reset chip. After removed it, the chip dont seem to reset anymore. Please someone can explain me what is wrong ? I can't find more information about how is pulled or not internnaly this pin.

Tank you.

RTC2CON   =  0x00;
COMPCON = 0x01; 	//Enable 25% of VDD (2.7v) soit 0.675v for wakeup voltage
hal_ancmp_set_ref_voltage_scale(HAL_ANCMP_REF_SCALE_25);//25%
CLKCTRL = CLKCTRL & 0xcf | 128; // Allow synthesis of 35khz clock
PWRDWN = 0x04;

I assume you meant you put a pullup resistor of 10k on the reset PIN of the chip ?

I don't see a problem of having 10k pull up on the reset pin. It should not related to the reason your chip resets. There is a pull-up internally, you don't really need a pull up externally. If you have one, make sure you don't let a ESD noise , such as hand touching to touch the pin.
