PRELIMINARY
15.3.
Each MCU has four byte-wide, bi-directional parallel ports that can be used general purpose I/O. Each port is
accessed through a corresponding special function register (SFR) that is both byte addressable and bit addressable.
When writing to a port, the value written to the SFR is latched to maintain the output data value at each pin. When
reading, the logic levels of the port’s input pins are returned regardless of the XBRn settings (i.e. even when the pin
is assigned to another signal by the Crossbar, the Port Register can always still read its corresponding Port I/O pin).
The exception to this is the execution of the
read-modify-write
instructions. The
read-modify-write
instructions
when operating on a port SFR are the following: ANL, ORL, XRL, JBC, CPL, INC, DEC, DJNZ and MOV, CLR or
SET, when the destination is an individual bit in a port SFR. For these instructions, the value of the port register (not
the pin) is read, modified, and written back to the SFR.
15.4.
Configuring Ports Which are not Pinned Out
P2 and P3 are not pinned out on the F001/06/11/16. P1, P2, and P3 are not pinned out on the F002/07/12/17. These
port registers (and corresponding interrupts, where applicable) are still available for software use in these reduced
pin count MCUs. Whether used or not in software, it is recommended not to let these port drivers go to high
impedance state. This is prevented after reset by having the weak pull-ups enabled as described in the XBR2
register. It is recommended that each output driver for ports not pinned out should be configured as push-pull using
the corresponding PRTnCF register. This will inhibit a high impedance state even if the weak pull-up is disabled.

(Note: When SDA, SCL, and RX appear on any of the P0 I/O, each are open-drain
regardless of the value of PRT0CF).
