26.4
26.4.1
The initial pin function is determined during reset configuration. The pin assignment registers allow the
user to select between digital I/O or another pin function after reset.
In single-chip mode, all pins are configured as digital I/O by default, except for debug data pins
(DDATA[3:0]) and processor status pins (PST[3:0]). These pins are configured for their primary functions
by default in all modes.
Every digital I/O pin is individually configurable as an input or an output via a data direction register
(DDRn).
Every port has an output data register (PORTn) and a pin data register (PORTnP/SETn) to monitor and
control the state of its pins. Data written to a PORTn register is stored and then driven to the corresponding
port n pins configured as outputs.
Reading a PORTn register returns the current state of the register regardless of the state of the
corresponding pins.
Reading a PORTnP/PSETn register returns the current state of the corresponding pins when configured as
digital I/O, regardless of whether the pins are inputs or outputs.
Every port has a PORTnP/SETn register and a clear register (CLRn) for setting or clearing individual bits
in the PORTn register.
In master mode, port A and B function as the upper external data bus, D[31:16]. When the PCDPA bit is
set, ports C and D function as the lower external data bus, D[15:0]. Ports E–J are configured to support
external memory functions.
The ports module does not generate interrupt requests.

Input data on all pins configured as digital I/O is synchronized to the rising edge of CLKOUT, as shown
