A class _psb
object is a resettable clock prescaler that can be connected to one of 3 possible clocks:
ioclk
;pll_32MHz
;pll_64MHz
;It is used in:
prescaler1
configure
:
Note 1 pll_32MHz
is not available when the PLL is used as system clock (HW_DEVICE_CLK_SRC
is "`rc_pll_16MHz`").
Note 2 pll_64MHz
is not available when supply voltage is below 2.7 V (HW_DEVICE_BODLEVEL
is "`1700_2000mV`").
Note 3 It is highly recommended that the counter is stopped whenever the prescaler clock is switched between "`pll_32MHz`" and "`pll_64MHz`".
Note 4 Turning the PLL on requires a special procedure that taked about 100 µs to execute.
Note 5 The PLL is never stopped once it has been turned on.
The reset
action resets the prescaler immediately without stopping it:
