LPC2131 SPI через SSP Опции

[Laptop]

Пытаюсь настроить передачу через SSP. Реакция нулевая...

void SSP_Init(void)
{
PINSEL1 |= 0x88; // configure SPI0 pins
SSPCR0 = 0x0007; // 8 bit
SSPCR1 = 0x02; // enable, master
SSPCPSR = 20; // SCK = 7.5 MHz, counter > 2 and even
}

unsigned char SSP_write (unsigned char data)
{
volatile unsigned char result;

result = SSPDR;
SSPDR = data; // send next SPI channel 0 data
while ((SSPSR & 0x10)) ; // wait for transfer completed
return result;

}
