we set CCLOCK to 60MHz, SSP0 divider is 2, so in lpc2300.s PCLKSEL1_Val should be 0x800.
// SSPCPSR clock prescale register, master mode, // minimum divisor is 0x02 SSP0CPSR = 0x06;
the clock freq. should be 60/2/6=5Mhz, but the measurement is 2.5MHz.
i checked SPI, calculation matches the measurement.
Do you have the experiences?
Thanks in advance
