[Solved] Timers not working in sleep mode

Hello all,
 
I have a PIC24FJ128GA306 on which I have a magnetic reed switch connected to an input assigned to T2CLK. The timer is essentially operating as a counter. However, it refuse to count when sleeping. If I replace the sleep instruction with a delay sequence then it will count fine. I am using this pic in a low power situation and would like to be able to go into sleep mode (having delays is not really a viable option). Sleep uses the watchdog timer to wake up.
 
The data sheet clearly states all timers will run in sleep mode either from LPRC or external clocking source (ie reed switch). Clearly I'm doing something wrong but I just can't figure it out. Extensive searching on the net reveals nothing. The pin shares functionality with RTCC out and an LCD controller pin but I have disabled both features (RTCC is running but output is disabled)
 
Here's the relevant code:
Initialisation:

void init_pulse(){  
 RPINR3bits.T2CKR = 2; //RD8 
 T2CONbits.T32 = 1; //32 bit mode  
 T2CONbits.TCS = 1; //External source  
 PR2 = 0xff;	PR3 = 0xff;  
 T2CONbits.TON = 1; //on  
 TMR2 = 0;  
 TMR3 = 0;  
 }  
    
 

 
Reading value:

pulse_count = TMR3HLD;  
 pulse_count  = pulse_count << 16;  
 pulse_count += TMR2;  
 TMR2 = 0;  
 TMR3HLD = 0;  
 volume = pulse_count * pulse_scalingf;

 
Sleep and/or delay:

for(i=0;i<sleep_cycles;i++)  
 {  
 asm volatile (	"CLRWDT\n"   
 "BSET RCON, #5\n" //wdt en  
 "NOP\n"   
 "NOP\n"   
 "NOP\n"   
 "PWRSAV #0");  
 }  
 //	for(i=0;i<35;i++)  
 //		__delay_ms(250);

 
Any help/hints would be greatly appreciated

Batgoy, you are correct it seems. I tested with Timer 1 and it works in sleep mode. It seems the sync block in the diagrams are the limiting factor. The datasheet threw me with this text in the timer 2/3 and 4/5 section:

They also support these features:
• Timer Gate Operation
• Selectable Prescaler Settings
• Timer Operation during Idle and Sleep modes
 • Interrupt on a 32-Bit Period Register Match

I don't see how timers 2/3 and 4/5 can run in sleep mode because they is a sync step in every possible configuration. It looks to me like a datasheet typo.
 
Well, it is solved now, although I don't get to use a 32bit timer/counter but I can work around that easily.
