UART IrDA Mode Receive Timing
Figure 88 shows the UART receive timing for IrDA mode, for a format of 8 data bits and 1 stop bit.
Table 89 describes the timing parameters (UA5–UA6) shown in the figure.

USBOTG Timing
This section describes timing for the USB OTG port and host ports. Both serial and parallel interfaces are
described.
3.7.20.1
USB Serial Interface Timing
The USB serial transceiver is configurable to four modes supporting four different serial interfaces:
DAT_SE0 bidirectional, 3-wire mode
DAT_SE0 unidirectional, 6-wire mode
VP_VM bidirectional, 4-wire mode
VP_VM unidirectional, 6-wire mode
The following subsections describe the timings for these four modes.
