A hardware-modification of a State Bit CC6xST is only possible while Timer T12 is
running (T12R = 1). If this is the case, the following rules apply for setting and resetting
the State Bits in Compare Mode (illustrated in Figure 18-11 and Figure 18-12):
A State Bit CC6xST is set to 1
• with the next T12 clock (f_T12) after a compare-match when T12 is counting up
(i.e., when the counter is incremented above the compare value);
• with the next T12 clock (f_T12) after a zero-match AND a parallel compare-match when
T12 is counting up.
A State Bit CC6xST is reset to 0
• with the next T12 clock (f_T12) after a compare-match when T12 is counting down
(i.e., when the counter is decremented below the compare value);
• with the next T12 clock (f_T12) after a zero-match AND NO parallel compare-match
when T12 is counting up.
