9.6.17 Parameter Register
Name: PARAMETER
Access Type: Read-only
Offset:0xF0
Reset Value: -
This register gives the configuration used in the specific device. Also refer to the Module Configuration section.
• DT: Digital Tuner
• 0: Digital tuner off
• 1: Digital tuner on
• DTREXPWA: Digital Tuner Exponent Writeable
• 0: Digital tuner exponent is a constant value. Writes to EXP bitfield in DTR will be discarded.
• 1: Digital tuner exponent is chosen by writing to EXP bitfield in DTR
• DTREXPVALUE: Digital Tuner Exponent Value
• Digital tuner exponent value if DT_EXP_WA is zero
• NUMAR: Number of Alarm Comparators
0: Zero alarm comparators.
1: One alarm comparator.
2: Two alarm comparators.
• NUMPIR: Number of Periodic Comparators
0: One periodic comparator.
1: Two periodic comparator.
• 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.
• PERnVALUE: Periodic Interval n Value
Periodic interval prescaler n tapping if PIRnWA is zero.
