I want to trim internal clock of KL05Z32.In reference document,I find AutoTrim machine.
my question is as follow:
1,is it right that the module must need a external clock? if there is on external clock in my board,can I trim internal clock?
2,How to trim the internal clock in freescale factory?
3,in reference,cpu will copy some value in flash to register.
But I create a new project.and i debug it with codewarrior10.3.I find 0x3fe-0x3ff is filled with 0xff.but MCGC3,MCG_C3 and MCG_C4(bit5:0) is not 0xff.Why?
4, will the trim value in flash be erased when I program my new program?
