4.3.1 Details of PCL timing

The delay elements LT, ST, LT, ST are used in sequence to generate four strobe periods referred to as ST1 through ST4. The last falling edge of ST is also used as a clock, referred to here as ST5.

It should not normally be necessary for users to concern themselves with the exact timing details, but the uses of the timing strobes are given in Table 2 on page as a guide for debugging purposes.

Figure 2 on page shows the waveforms for the long (LT) and short (ST) timers. The UAT timer is not shown as it may occur at different times, depending on the operation.
