Figure 18-28 T13 State Bit Block Diagram
The inputs to the set/reset logic for the CC6xST bits are the timer run bit (T13R), the
timer zero-match signal (T13_ZM), the end-of-single-shot mode signal (T13_SSEP), and
the actual individual compare-match signal CM_63. In addition, the state bit can be set
or reset by software via the set and reset bits, MCC63S and MCC63R.
A modification of the State Bit CC63ST by hardware is only possible while Timer T13 is
running (T13R = 1). If this is the case, the following rules apply for setting and resetting
the State Bit in Compare Mode:
State Bit CC63ST is set to 1
• with the next T13 clock (f_T13) after a compare-match (T13 is always counting up)
(i.e., when the counter is incremented above the compare value);
• with the next T13 clock (f_T13) after a zero-match AND a parallel compare-match.
State Bit CC63ST is reset to 0
• with the next T13 clock (f_T13) after a zero-match AND NO parallel compare-match.
