Denotes the default value out of reset.This value should be used to disable the RTI to ensure future backwards compatibility.
Decimal or Binary Divider Select Bit — RTDEC selects decimal or binary based prescaler values.
Real Time Interrupt Prescale Rate Select Bits — These bits select the prescale rate for the RTI. See
Table
Real Time Interrupt Modulus Counter Select Bits — These bits select the modulus counter target value to provide additional
granularity.Table 354
