ADSP-21267
Timer PWM_OUT Cycle Timing
The following timing specification applies to Timer[2:0] in
PWM_OUT (pulse width modulation) mode. Timer signals are
routed to the DAI_P[20:1] pins through the SRU. Therefore, the
timing specifications provided below are valid at the
DAI_P[20:1] pins.
Table 13. Timer[2:0] PWM_OUT Timing
Timer WDTH_CAP Timing
The following timing specification applies to Timer[2:0] in
WDTH_CAP (pulse width count and capture) mode. Timer sig-
nals are routed to the DAI_P[20:1] pins through the SRU.
Therefore, the timing specifications provided below are valid at
the DAI_P[20:1] pins.
