This bit is set when a 0 to 1 transition on POSCSR.BOD33DET bit is detected:
going below BOD33 reference value.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set when a 0 to 1 transition on POSCSR.BODDET bit is detected:
below BOD reference value.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set when a 0 to 1 transition on the POSCSR.OSC32RDY bit is detected:
ready to be used as clock source.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set when a 0 to 1 transition on the POSCSR.OSC1RDY bit is detected:
as clock source.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set when a 0 to 1 transition on the POSCSR.OSC1RDY bit is detected:
as clock source.
This bit is cleared when the corresponding bit in ICR is written to one.
This bit is set when a 0 to 1 transition on the POSCSR.MSKRDY bit is detected:
(CPU/HSB/PBA/PBB)_MASK registers.
This bit is cleared when the corresponding bit in ICR is written to one.
0: The CKSEL register has been written, and the new clock setting is not yet effective.
1: The synchronous clocks have frequencies as indicated in the CKSEL register.
Note: Writing a one to ICR.CKRDY has no effect.
