NOTE
All the timings for the SSI are given for a non-inverted serial clock
polarity (TSCKP/RSCKP = 0) and a non-inverted frame sync
(TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have
been inverted, all the timing remains valid by inverting the clock signal
STCK/SRCK and/or the frame sync STFS/SRFS shown in the tables
and in the figures.
All timings are on Audiomux Pads when SSI is being used for data
transfer.
“Tx” and “Rx” refer to the Transmit and Receive sections of the SSI.
The terms WL and BL refer to Word Length (WL) and Bit Length (BL).
For internal Frame Sync operation using external clock, the FS timing is
same as that of Tx Data (for example, during AC97 mode of operation).

UART I/O Configuration and Timing Parameters
4.7.18.1
UART RS-232 I/O Configuration in Different Modes
The i.MX53xA UART interfaces can serve both as DTE or DCE device. This can be configured by the
DCEDTE control bit (default 0 – DCE mode). Table 88 shows the UART I/O configuration based on the
enabled mode.
4.7.18.2
UART RS-232 Serial Mode Timing
The following sections describe the electrical information of the UART module in the RS-232 mode.
4.7.18.2.1
UART Transmitter
Figure 87 depicts the transmit timing of UART in the RS-232 serial mode, with 8 data bit/1 stop bit format.
Table 89 lists the UART RS-232 serial mode transmit timing characteristics.
