Some of the oldest LPC21xx had external interrupt triggered on level, not edge.
/01 and later seemed to add two registers to control the desired interrupt
conditions such as rising/falling edge.
It amazes me how many people post questions here having never done their
research on the data sheets. It's OK to ask, having done so and not found
the answer. Same thing for the person here who asked if there were military
extended temperature range NXP products.
But gosh, there are a lot of lazy or stupid people out there.

I am not sure if I understand your question correctly. Doesn't the user
manual give an answer for your question by saying: "Note: EINT3 channel
is shared with GPIO interrupts" (page 93) or "GPIO0 and GPIO2 interrupts
share the same VIC slot with the External Interrupt 3 event" (page 171)?

First of all Thanks.
Second thing is, i have not found any ISR of GPIO0 and GPIO2 interrupt , which
will get executed on getting any edge type interrupt on GPIO. r they just for
making the controller out of Power Down Mode only?
Thanks.

User manual page 171, "2.2 Interrupt generating digital ports" last
bullet or page 93 "6. Interrupt sources"...

Today when i am reading the user manual of LPC23xx for LPC2378. i have found
that we can generate interrupt on GPIO 0 and 2 ports. But i have not found any
VICVectAddr crossponding to port interrupt. then how can i generate interrupt by
GPIO. here i am not talking about external interrupt like
EINT0,EINT1,EINT2,EINT3.
