interrupt requests are recognized during the following cycle. If these
flags are polled, a transition at CT0I or CT1I will be recognized one
cycle before a transition on CT2I or CT3I since registers are read
during S5. The CMI0, CMI1, and CMI2 flags are set during S6 of the
cycle following a match. CMI0 is scanned by the interrupt logic
during S2; CMI1 and CMI2 are scanned during S3 and S4. A match
will be recognized by the interrupt logic (or by polling the flags) two
cycles after the match takes place.
The 16-bit overflow flag (T2OV) and the byte overflow flag (T2BO)
are set during S6 of the cycle in which the overflow occurs. These
flags are recognized by the interrupt logic during the next cycle.
Special function register IP1 (Figure 8) is used to determine the
Timer T2 interrupt priority. Setting a bit high gives that function a
high priority, and setting a bit low gives the function a low priority.
The functions controlled by the various bits of the IP1 register are
shown in Figure 8.
