Feature test: Seamless Auto SCK from 4MHz-488Hz (support Target MCU clock from 16MHz to 1.9kHz);

Auto SCK from 8M-16k VS Speed:

8M-CPU-2M-sck:
(7162+6)/0.6=11946

1M-CPU-250k-sck:
(7162+6)/1.46=4909

128k-CPU-31k-sck:
(7162+6)/11.05=648

16k-CPU-4k-sck:
(7162+6)/131.11=54

m88p fuse to cpu clock settings:
0x63 == 16kHz
0xe3 == 128kHz
0x62 == 1MHz
0xE2 == 8MHz
