SLOW_INT_DIV
RW
R
0
Specifies the slow clock divider (from the peripheral
clock 'clk_peri' to the slow clock 'clk_slow'). Integer
division by (1+SLOW_INT_DIV). Allows for integer
divisions in the range [1, 256] (SLOW_INT_DIV is in
the range [0, 255]).
Note that this field is retained. However, the counter
that is used to implement the division is not and will be
initialized by HW to '0' when transitioning from
DeepSleep to Active power mode.
24:31 PERI_INT_DIV
RW
R
0
Specifies the peripheral clock divider (from the high
frequency clock 'clk_hf' to the peripheral clock
'clk_peri'). Integer division by (1+PERI_INT_DIV).
Allows for integer divisions in the range [1, 256]
(PERI_INT_DIV is in the range [0, 255]).
Note that this field is retained. However, the counter
that is used to implement the division is not and will be
initialized by HW to '0' when transitioning from
DeepSleep to Active power mode.
Note that Fperi <= Fperi_max. Fperi_max is likely to be
smaller than Fhf_max. In other words, if Fhf =
Fhf_max, PERI_INT_DIV should not be set to '0'.
