which can be selected under software control.
These pins are dedicated 20 mA I/O pins – no secondary functions
These pins are either combined with PE[2:0] to form a 7-bit port, or they are pro-
grammed to be the I
This is a general-purpose port. – This port shares pins with secondary functions,
which can be selected under software control.
These are general-purpose ports. – These ports share pins with XA [22:0] and are
not available when using external memory
These are general-purpose ports. – These ports share pins with XD [31:0] are not
available when using external memory
This is a general-purpose port. – This port is not available when using external
memory.
These pins are part of general-purpose ports PO[4:0] – These pins are not available
when using external memory functions (OE_N, WR_N)
These pins are part of general-purpose ports PO[4:0] – They shares pins with the
startup external memory function, so it is disabled at power up.

Clear To Send – Indicates that modem or data set is ready to transfer data.
Data Set Ready – Indicates that modem or data set is ready to establish a commu-
nications link with UART.
Data Set Ready – Indicates that modem or data set is ready to establish a commu-
nications link with UART.
Data Terminal Ready – Indicates that UART is ready to establish a communications
link with the modem or data set.
