How to wakeup with analogComparator on nRF24LE1

[robotox]

Hi,

i try without succes to go into MemoryRentention Timer On sleep mode, and wakeup with the analog comparator activated by AIN1 without sucess. Here is my code, please can you tell me what is wrong ?

Please can you show me correct sequence to enter and output this mode with the analog comparator ?

Tank you !

IEN0  = 0x00; 									//disable global interrupt
IEN1  = 0x00; 									//disable tick interrupt

CLKCTRL =  128;
CLKLFCTRL =  	0x01;     							//Enable 32768 clock synthesi
ADCCON1 =  0x05;                                    // AIN1 > 0.25*VDD
COMPCON = 0x01;                                    //Enable comparator and configure selected pin as analog input
PWRDWN = 0x03;  	                                   /*  3->Memory retention timerOn */
while(1); /*zZZzzZZZz*/

Hi robotox,

Please try to use Memory retention, timers on mode PWRDWN = 0x04; to check if that help. We found that it was a bug with our chip when you use analog comparator it may mess up with the brownout reset. The issue doesn't happens with the OTP chip.

This code worked for me:

hal_ancmp_set_input_channel(8);//P1.0
hal_ancmp_set_ref_voltage_scale(0x01);//50%
hal_ancmp_set_reference(0);
hal_ancmp_enable(true);
PWRDWN=0x04;

is there a revision planned or a batch that do not have the bug ?
