10.5.2 Output Control Block

The output control block prepares the value of the OUTx signal, which is
latched into the OUTx flip-flop with the next positive timer clock edge, as shown
in Figure 10–23 and Table 10–2. The equal signals EQUx and EQU0 are
sampled during the negative level of the timer clock, as shown in Figure 10–23.
