Lpc2000

Hello,

I'm working with IAP and as recommended by the LPC2119 manual I'm 
disabling all the interrupts I use (TIMER0 and CAN1 Rx) before any 
erase or write operation on the Flash.

Everything's working fine, the only "problem" is that sometimes it 
takes some time(~20-30sec.) for the interrupts to wake up the first 
time I disable them.

This is the process the 1st time I disable interrupts:
1.- Disable Interrupts
2.- Erase sectors (1..14)
3.- Enable Interrupts
4.- Send CAN Message
.........delay here........
5.- Receive CAN Message

I know the delay is not while erasing sectors because I actually see 
that my CAN msg it's received... but I can't detect any CAN msg sent 
to me until that ~20-30sec.

A few steps ahead I disable/enable the ints. to program the Flash, 
and this time it all works without any delay.

Does anyone have any idea of what might be happening?

Thanks in advance,
Gonzalo
