TMRx_RR_H and TMRx_RR_L. Downcounting continues on the next clock edge and
the timer continues to count until disabled. An example of the timer operating in
CONTINUOUS mode is displayed in

Table 51. Example: PRT CONTINUOUS Mode Parameters
Timer Interrupts
The terminal count flag (TMRx_IIR[EOC]) is set to 1 whenever the timer reaches
its end-of-count value in SINGLE PASS mode, or when the timer reloads the start value in
CONTINUOUS mode. The terminal count flag is only set when the timer reaches
(or reloads) from
with the value
The CPU is programmed to poll the EOC bit for the time-out event. Alternatively, an inter-
rupt service request signal is sent to the CPU by setting the TMRx_IER[EOC] bit to 1.
