lpc23xx uart kesme

[armsistem]

Arkadaşlar merhaba , lpc2365 uart0 veri geldiğinde kesme oluşmasını istiyorum . Kod aşağıda fakat kesme oluşmuyor harici başka ayar yapmam gerekiyor mu ?

Gerbay hocam , interrupt ayarı aşağıda;

  U0IER = 0x03;//

Kesme rutini aşağıda ;Uart0 veri gönderiyorum, lakin kesmeden hiç çıkmıyor,sürekli

       string_gonder_u0("/* Receive Data Available */");karakter_gonder_u0(0x0d);

  ekrana basıyor ,uart0 clear interrup şeklinde bir şey bulamadım ?
