in the users manual UM10912 of the LPC54608 in chapter 8.4 (PowerLib API) there is the following function described:
void CLOCK_SetupFROClocking(uint32_t iFreq);
I am using ARM/Keil and downloaded the actual SDK 2.2 for the LPC54608. It includes the powerlib in ARM version named "keil_lib_power.lib". This library does not contain this function CLOCK_SetupFROClocking.
I can find a function of this name in "drivers\fsl_clocks.c", but this version does something which does not fit to the users manuals description of the register FROCTRL (it uses undocumented fields in the register FROCTRL etc).
- Is there somewhere a powerlib which contains this function? The users manual does not explain what has to be done to activate the FROHF clock (48/96MHz), it only refers to the powerlib function CLOCK_SetupFROClocking.
- In the powerlib of the SDK there exist plenty of functions which are not documented in the users manual. Is there somewhere a documentation of this library?
Thanks for your help!
