5-ctimer
This bit is set when the output of the chosen stage becomes active;
an interrupt request will be generated if RTIE is set. When set, the bit
may be cleared by writing a ‘0’ to it.
CTOE — Core timer overflow interrupt enable
1 = A core timer overflow interrupt will be generated if CTOF is set
and the I-bit in the CCR is clear.
0 = No core timer overflow interrupt will be generated regardless of
the state of the CTOF flag and the I-bit.
RTIE — Real time interrupt enable
0 = A real time interrupt will be generated if RTIF is set and the I-bit
in the CCR is clear.
0 = No real time interrupt will be generated regardless of the state
of the RTIF flag and the I-bit.
RT1, RT0 — Real time interrupt rate select
These two bits select one of four taps from the real time interrupt
circuitry. Reset sets both RT0 and RT1 to one, selecting the lowest
periodic rate and therefore the maximum time in which to alter them if
necessary. The COP reset times are also determined by these two
bits. Care should be taken when altering RT0 and RT1 if a timeout is
imminent, or if the timeout period is uncertain. If the selected tap is
modified during a cycle in which the counter is switching, an RTIF
could be missed or an additional one could be generated. To avoid
problems, the COP should be cleared before changing the RTI taps.
