RTR[1:0] —Real-Time Interrupt (RTI) Rate
Refer to
10.1 Real-Time Interrupt
.
10.1 Real-Time Interrupt
These rates are a function of the MCU oscillator frequency and the value of the software-accessible
control bits, RTR1 and RTR0. These bits determine the rate at which interrupts are requested by the
RTI system. The RTI system is driven by an E divided by 2
13
rate clock compensated so that it is inde-
pendent of the timer prescaler. The RTR1 and RTR0 control bits select an additional division factor. RTI
is set to its fastest rate by default out of reset and can be changed at any time.
