Periodically sampled and not 100% tested.
RESET duration is measured during the time in which RESET is asserted, V
valid. When the V
the device circuitry will not be in an initialized state that can result in significant power consumption and heat-up. Designs
should minimize this state to the shortest possible duration.
If PLL does not lose lock.
When using fast interrupts and IRQA, IRQB, IRQC, and IRQD are defined as level-sensitive, timings 19 through 21 apply to
prevent multiple interrupt service. To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended
when using fast interrupts. Long interrupts are recommended when using Level-sensitive mode.
WS = number of wait states (measured in clock cycles, number of T
Use expression to compute maximum value.
This timing depends on several settings:
For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time will be defined
by the PCTL Bit 17 and OMR Bit 6 settings.
For PLL enable, if PCTL Bit 17 is 0, the PLL is shutdown during Stop. Recovering from Stop requires the PLL to get locked.
The PLL lock procedure duration, PLL Lock Cycles (PLC), may be in the range of 0 to 1000 cycles. This procedure occurs
in parallel with the stop delay counter, and stop recovery will end when the last of these two events occurs: the stop delay
counter completes count or PLL lock procedure completion.
PLC value for PLL disable is 0.
The maximum value for ET
4096/150 MHz = 27.3 µs). During the stabilization period, T
timing may vary as well.
