User manual
3.2.10 PLL and Power-down mode
3.2.11 PLL frequency calculation
3.2.9 PLL Feed register (PLLFEED - 0xE01F C08C)
A correct feed sequence must be written to the PLLFEED register in order for changes to
the PLLCON and PLLCFG registers to take effect. The feed sequence is:
The two writes must be in the correct sequence, and must be consecutive APB bus
cycles. The latter requirement implies that interrupts must be disabled for the duration of
the PLL feed operation. If either of the feed values is incorrect, or one of the previously
mentioned conditions is not met, any changes to the PLLCON or PLLCFG register will not
become effective.
Table 49.
Power-down mode automatically turns off and disconnects the PLL. Wakeup from
Power-down mode does not automatically restore the PLL settings, this must be done in
software. Typically, a routine to activate the PLL, wait for lock, and then connect the PLL
can be called at the beginning of any interrupt service routine that might be called due to
the wakeup. It is important not to attempt to restart the PLL by simply feeding it when
execution resumes after a wakeup from Power-down mode. This would enable and
connect the PLL at the same time, before PLL lock is established.
The PLL equations use the following parameters:
Table 50.
The PLL output frequency (when the PLL is both active and connected) is given by:
F
The PLL inputs and settings must meet the following:
