Timer WDTH_CAP Timing
The following timing specification applies to timer0, and
timer1, and in WDTH_CAP (pulse width count and capture)
mode. Timer signals are routed to the DPI_P14–1 pins through
the SRU. Therefore, the timing specification provided below is
valid at the DPI_P14–1 pins.
Table 20. Timer Width Capture Timing
Pin to Pin Direct Routing (DAI and DPI)
For direct pin connections only (for example DAI_PB01_I to
DAI_PB02_O).
