PLLCFG on ARM7_LPC2129_IAR demo
Hi all,
It’s correct PLLCFG on ARM7_LPC2129_IAR demo or must be PLLCFG = 0x24 ?
On FreeRtos 5.4.0 demo project:
Fosc : 12Mhz
CCLK : 60Mhz
PLLCFG = 0x04
If it’s not correct there’s a big problem?
Regards
Carlos

The PLL output frequency is given by:
Fcco = Fosc * M * 2 * P
which given the value 0x24 in PLLCFG gives:
120MHz = 12000000 * 5 * 2 * 1
which would indeed appear to be wrong, but the demo seems to run at the right frequency which must be fluke.
Regards.
