Serial Ports
In slave transmitter mode and master receiver mode the maxi-
mum serial port frequency is fPCLK/8. To determine whether
communication is possible between two devices at clock speed
n, the following specifications must be confirmed: 1) frame sync
delay and frame sync setup and hold, 2) data delay and data
setup and hold, and 3) serial clock (SCLK) width.
Serial port signals are routed to the DAI_P20–1 pins using the
SRU. Therefore, the timing specifications provided below are
valid at the DAI_P20–1 pins. In Figure 24 either the rising edge
or the falling edge of SCLK (external or internal) can be used as
the active sampling edge.
