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 21. 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).
