Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
26
FIRCERR
Fast IRC Clock Error
This flag is reset on Chip POR only, software can also clear this flag by writing a logic one
0
Error not detected with the Fast IRC trimming.
1
Error detected with the Fast IRC trimming.
25
FIRCSEL
Fast IRC Selected status
0
Fast IRC is not the system clock source
1
Fast IRC is the system clock source
24
FIRCVLD
Fast IRC Valid status
0
Fast IRC is not enabled or clock is not valid.
1
Fast IRC is enabled and output clock is valid. The clock is valid once there is an output clock from the
FIRC analog.
23

Fast IRC Trim Update
0
Disable Fast IRC trimming updates
1
Enable Fast IRC trimming updates
8
FIRCTREN
Fast IRC Trim Enable
0
Disable trimming Fast IRC to an external clock source
1
Enable trimming Fast IRC to an external clock source
7–4
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
3
FIRCREGOFF
Fast IRC Regulator Enable
0
Fast IRC Regulator is enabled.
1
Fast IRC Regulator is disabled.
2
FIRCLPEN
Fast IRC Low Power Enable
0
Fast IRC is disabled in VLP modes
1
Fast IRC is enabled in VLP modes
1
FIRCSTEN
Fast IRC Stop Enable
0
Fast IRC is disabled in Stop modes. When selected as the reference clock to the System PLL and if
the System PLL is enabled in STOP mode, the Fast IRC will stay enabled even if FIRCSTEN=0.
1
Fast IRC is enabled in Stop modes
0
