Hi,
Who can tell me the interrupt response time about LPC2132? 
In my system, one rising edge causes the capture interrupt. The 
delay between the rising edge and getting capture value is critical: 
less than 1uS!!
Who know this time? Whether the LPC2132 is suitable for this project?

Hi,

this is not interrupt response time if I get your answer correctly.
Are you asking whether the capture happens within less than 1 usec,
the answer is depending on your oscillator speed and te setting of
VPBDIV. Assuming VPBDIV = 1 and running at 60 MHz (that is the fastest
you can get), you will have captured the value in approx. 100ns.
