Prescaler Divider

•

A hardware RESET puts the prescaler divider in the following state:

•CKRL = FFh: FCLK CPU = FCLK PERIPH = FOSC/2 (Standard C51 feature)

•

Any value between FFh down to 00h can be written by software into CKRL register

in order to divide frequency of the selected oscillator:

•

CKRL = 00h: minimum frequency

FCLK CPU = FCLK PERIPH = FOSC/1020 (Standard Mode)

FCLK CPU = FCLK PERIPH = FOSC/510 (X2 Mode)

•

CKRL = FFh: maximum frequency

F

CLK CPU = FCLK PERIPH = FOSC/2 (Standard Mode)

CLK CPU = FCLK PERIPH = FOSC (X2 Mode)
