Table 29. PRT SINGLE PASS Mode Operation Example
Continuous Mode
In CONTINUOUS mode, when the end-of-count value,
matically reloads the 16-bit start value from the Timer Reload registers, TMRx_RR_H and
TMRx_RR_L. Downcounting continues on the next clock edge. In CONTINUOUS mode,
the PRT continues to count until disabled. An example of a PRT operating in CONTINU-
OUS mode is displayed in
