Dear Friends,
I have a quick question regarding SPI Clock rate on LPC2129.
I am using in 10Mhz input to the controller, cclk is 60Mhz, and Pclk at 30Mhz.
Multiplier at 5, and Divider 2.
Have configured SPI to maximum possible clock rate by placing 0x08 into SPI Clock counter register.
So I am expecting a 3.75Hhz clock output from SPI(Pclk/8). When I measured this, it only a 1Mhz clock on SPI. I struggling to find out whats really happening.
My SPI is connected to Micro SD. Is there any thing like, Max spi clock rate on LPC2129?
I will be thankful for your suggestions and register configuration if any.
