Programming ics307

[ambrella]

Hi! I have problem with ics307-02.
I try write 3 byte 0x23 0x14 0x06, using the emulator SPI interface.

        STROBE_L;
        sendByte( 0x23 );
        sendByte( 0x14 );
        sendByte( 0x06 );
        DATA_L;
        STROBE_H;  // Strobe High
        Delay();
        STROBE_L;  // Strobe low

sendByte function:

void sendByte(uint8_t data)
{
    uint8_t BitValue = 128;

    Delay();

    for(int i = 0; i < 8; i++)
    {
        SCLK_L;
        Delay();

        if(data & BitValue > 0)DATA_H; else DATA_L;

        Delay();
        SCLK_H;
        Delay();
        SCLK_L;

        BitValue = BitValue / 2;
    }
    Delay();
}

Af written bytes frequency does not change. Who worked with ics307? Who are some ideas?
