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
TP, don't you think you should at least tell us what processor you are using? what is your Xtal? how can anybody answer your questions without these essential details? please post the entire configuration part and I'll have a look into it (if it is a STR9/7).
