Note1: When the setting is modified, confirm whether the written value has been reflected to the [CGOSCCR]
<OSCF> bit before executing the next operation.
Note2: Setting cannot be changed, when it is [SIWDxOSCCR]<OSCPRO> =1 (Write protect of SIWDT is
effective)
Note3: When using the oscillator connection, set this bit to "01"(external high speed oscillator).
After reset Type
0 R Read as "0".
Control write-protection for the CG register (all registers except for
this register)
0xC1 R/W
0xC1:
Other than 0xC1: Sets write protection (Protect enable)
After reset Type
0 R Read as "0".
Indicates the stability flag of internal oscillation for IHOSC2
0 R
0: Stopping or being in warming-up
1: Stable oscillation
0 R Read as "0".
Indicates the stability flag of internal oscillation for IHOSC1
1 R
0: Stopping or being in warming-up
1: Stable oscillation
0 R Read as "0".
0 R/W Write as "0"
0 R Read as "0".
Indicates high speed oscillator for f
0 R 0: Internal high speed oscillator 1 (IHOSC1)
1: External high speed oscillator (EHOSC)
Selects a high speed oscillation for f
0 R/W
0: Internal high speed oscillator 1 (IHOSC1)
1: External high speed oscillator (EHOSC)
0 R Read as "0".
