Serial Ports
To determine whether communication is possible between two
devices at clock speed n, the specifications in
Table 24
,
Table 25
,
Table 26
,
Table 27
,
Figure 21
, and
Figure 22
must be confirmed:
1) frame sync delay and frame sync setup and hold; 2) data delay
and data setup and hold; and 3) SCLK width.
Serial port signals (SCLK, FS, DxA,/DxB) are routed to the
DAI_P20
1 pins using the SRU. Therefore, the timing specifi-
cations provided below are valid at the DAI_P20
1 pins.
