Table 25.
The PLL0 output frequency (when PLL0 is both active and connected) is given by:
F
PLL inputs and settings must meet the following:
The equation can be solved for other PLL parameters:
M = (F
N = (2 × M × F
F
Allowed values for M:
At higher oscillator frequencies, in the MHz range, values of M from 6 through 512 are
allowed. This supports the entire useful range of both the main oscillator and the IRC.
For lower frequencies, specifically when the RTC is used to clock PLL0, a set of 65
additional M values have been selected for supporting baud rate generation, CAN
operation, and obtaining integer MHz frequencies. These values are shown in
