I/O Port SFRs
The I/O ports provide digital input sensing, output drive, pin
interrupts, connectivity for analog inputs and outputs, LCD, and
access to peripherals through the DSI. Full information on I/O
ports is found in
I/O ports are linked to the CPU through the PHUB and are also
available in the SFRs. Using the SFRs allows faster access to a
limited set of I/O port registers, while using the PHUB allows boot
configuration and access to all I/O port registers.
Each SFR supported I/O port provides three SFRs:
5.7.3.1 xdata Space
The 8051 xdata space is 24-bit, or 16 MB in size. The majority of
this space is not “external”—it is used by on-chip components.

accessed using the EMIF. See

Document Number: 001-53413 Rev. *L
SFRPRTxDR sets the output data state of the port (where × is
port number and includes ports 0–6, 12 and 15).
The SFRPRTxSEL selects whether the PHUB PRTxDR
register or the SFRPRTxDR controls each pin’s output buffer
within the port. If a SFRPRTxSEL[y] bit is high, the
corresponding SFRPRTxDR[y] bit sets the output state for that
pin. If a SFRPRTxSEL[y] bit is low, the corresponding
PRTxDR[y] bit sets the output state of the pin (where y varies
from 0 to 7).
The SFRPRTxPS is a read only register that contains pin state
values of the port pins.
