LPC2214 не генериться прерывание SPI Опции

[Slider_spb]

Идея в следующем:
Используються прерывания Timer0 Uart0 EINT0 I2C SPI0

Все прерывания проходят кроме SPI0
Причём первый байт принимаеться правильно флаг прерывания разрешён и выставляеться
но по вектору прерывания не обращается....

значение регистров после принятия данных...

S0SPCR = 0x90;
S0SPSR =0xA0;
S0SPDR =0x35; // превильно принятый байт

S0SPINT=0x01;

ниже выборка кода
