This register gives the configuration used in the specific device. Also refer to the Module Configuration section.
• PERnVALUE: Periodic Interval n Value
Periodic interval prescaler n tapping if PIRnWA is zero.
• PIRnWA: Periodic Interval n Writeable
0: Periodic interval n prescaler tapping is a constant value. Writes to INSEL field in PIRn register will be discarded.
1: Periodic interval n prescaler tapping is chosen by writing to INSEL field in PIRn register.
• NUMPIR: Number of Periodic Comparators
0: One periodic comparator.
1: Two periodic comparator.
• NUMAR: Number of Alarm Comparators
0: Zero alarm comparators.
1: One alarm comparator.
2: Two alarm comparators.
• DTREXPVALUE: Digital Tuner Exponent Value
Digital tuner exponent value if DTEXPWA is zero.
• DTREXPWA: Digital Tuner Exponent Writeable
0: Digital tuner exponent is a constant value. Writes to EXP field in DTR will be discarded.
1: Digital tuner exponent is chosen by writing to EXP field in DTR.
• DT: Digital Tuner
0: Digital tuner not implemented.
1: Digital tuner implemented.
