The Power Management Controller is capable of handling up to four Programmable Clocks,
PCK0 to PCK3.
A Programmable Clock is generally multiplexed on a PIO Controller. The user must first program
the PIO controllers to assign the pins of the Programmable Clock to its peripheral function.
The Power Management Controller has an interrupt line connected to the Advanced Interrupt
Controller (AIC). Handling the PMC interrupt requires programming the AIC before configuring
the PMC.
The electrical characteristics of the embedded oscillators and PLLs are product-dependent,
even if the way to control them is similar.
All of the parameters for both oscillators and the PLLs are given in the DC Characteristics sec-
tion of the product datasheet. These figures are used not only for the hardware design, as they
affect the external components to be connected to the pins, but also the software configuration,
as they determine the waiting time for the startup and lock times to be programmed.
The Power Management Controller provides and controls up to thirty peripheral clocks. The bit
number permitting the control of a peripheral clock is the Peripheral ID of the embedded
peripheral.
When the Peripheral ID does not correspond to a peripheral, either because this is an external
interrupt or because there are less than thirty peripherals, the control bits of the Peripheral ID
are not implemented in the PMC and programming them has no effect on the behavior of the
PMC.
The Power Management Controller provides and controls two USB Clocks, the UHPCK for the
USB Host Port, and the UDPCK for the USB Device.
If the product does not embed either the USB Host Port or the USB Device Port, the associated
control bits and registers are not implemented in the PMC and programming them has no effect
on the behavior of the PMC.
