16.2.1 UART3 Package Dependency
16.1 Introduction
16.2 Implementation Details
UART3 implements both a UART and an HDLC interface identical to that of UART1; it does
not implement the modem interface. An additional output signal, TENn, is provided to support
RS-485 operation by providing direction control of external data transceivers. The OUT1 and
OUT2 signals in the MCR register define the TENn operating mode. TENn can be configured
to assert whenever the UART transmit buffer has data to send, or to operate under software
control.
For additional details about UART1, refer to
Control Signals” on page
UART3 uses package pins RXD2, TXD2 and EGPIO[3]. See
The use of EGPIO[3] is determined by several bits in Syscon register DeviceCfg. See
Table 16-2
Note: This chapter applies only to the EP9307, EP9312, and EP9315 processors.
