Timer WDTH_CAP Timing
The following timing specification applies to Timer0, Timer1,
and Timer2 in WDTH_CAP (pulse width count and capture)
mode. Timer signals are routed to the DPI_P14–1 pins through
the DPI SRU. Therefore, the timing specification provided
below are valid at the DPI_P14–1 pins.
Table 19. 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).
