Design Considerations
Oscillators Control
PwdOscA and PwdOscB signals are generated in the Clock generator and used to
control the hard blocks of oscillators A and B.
PwdOscA =’1’ stops OscA
PwdOscB =’1’ stops OscB
The following tables summarize the Operating modes:
Prescaler Divider
A hardware RESET puts the prescaler divider in the following state:
CKRL = FFh: FCLK CPU = FCLK PERIPH = FOSCA/2 (Standard C51 feature)
CKS signal selects OSCA or OSCB: FCLK OUT = FOSCA or FOSCB
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 = FOSCA/1020 (Standard Mode)
FCLK CPU = FCLK PERIPH = FOSCA/510 (X2 Mode)
CKRL = FFh: maximum frequency
FCLK CPU = FCLK PERIPH = FOSCA/2 (Standard Mode)
FCLK CPU = FCLK PERIPH = FOSCA (X2 Mode)
