If EREFSTEN is set and the ERCLKEN bit is written to 1, the external reference clock will keep running
during stop mode in order to provide a fast recovery upon exiting stop.
8.4.7
The ICS presents the divided FLL reference clock as ICSFFCLK for use as an additional clock source for
peripheral modules. The ICS provides an output signal (ICSFFE) which indicates when the ICS is
providing ICSOUT frequencies four times or greater than the divided FLL reference clock (ICSFFCLK).
In FLL Engaged mode (FEI and FEE) this is always true and ICSFFE is always high. In ICS Bypass
modes, ICSFFE will get asserted for the following combinations of BDIV and RDIV values:
Freescale Semiconductor
Fixed Frequency Clock
BDIV=00 (divide by 1), RDIV ≥ 010
BDIV=01 (divide by 2), RDIV ≥ 011
BDIV=10 (divide by 4), RDIV ≥ 100
BDIV=11 (divide by 8), RDIV ≥ 101
