Set to 1 when 0 to 1 transition on POSCSR:BODDET bit is detected:
BOD reference value.
Set to 1 when 0 to 1 transition on the POSCSR:OSC32RDY bit is detected:
used as clock source.
Set to 1 when 0 to 1 transition on the POSCSR:OSC1RDY bit is detected:
clock source.
Set to 1 when 0 to 1 transition on the POSCSR:OSC1RDY bit is detected:
clock source.
Set to 1 when 0 to 1 transition on the POSCSR:MSKRDY bit is detected:
(CPU/HSB/PBA/PBB)_MASK registers.
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 ICR:CKRDY to 1 has no effect.
Set to 1 when 0 to 1 transition on the POSCSR:LOCK1 bit is detected:
source.
Set to 1 when 0 to 1 transition on the POSCSR:LOCK0 bit is detected:
source.
