Port 0
DPort 0 is an 8-bit open drain bidirectional I/O port. As an output port each pin
can sink 8 LS TTL inputs. Port 0 pins that have 1s written to them float, and in that
state can be used as high-impedance inputs.
Port 0 is also the multiplexed low-order address and data bus during accesses to
external program memory if EBEN is pulled low. During accesses to external Data
Memory, Port 0 always emits the low-order address byte and serves as the multiplexed
data bus. In these applications it uses strong internal pullups when emitting 1s.
Port 0 also outputs the code bytes during program verification. External pullups are
required during program verification.

Port 1
DPort 1 is an 8-bit bidirectional I/O port with internal pullups. Port 1 pins that
have 1s written to them are pulled high by the internal pullups, and in that state can be
used as inputs. As inputs, Port 1 pins that are externally being pulled low will source
current (I
IL
, on the data sheet) because of the internal pullups.
Port 1 also serves the functions of various special features of the 8XC152, as listed
below:

Port 2
DPort 2 is an 8-bit bidirectional I/O port with internal pullups. Port 2 pins that
have 1s written to them are pulled high by the internal pullups, and in that state can be
used as inputs. As inputs, Port 2 pins that are externally being pulled low will source
current (I
IL
, on the data sheet) because of the internal pullups.
Port 2 emits the high-order address byte during fetches from external Program
Memory if EBEN is pulled low. During accesses to external Data Memory that use 16-
bit addresses (MOVX
@
DPTR and DMA operations), Port 2 emits the high-order
address byte. In these applications it uses strong internal pullups when emitting 1s.
During accesses to external Data Memory that use 8-bit addresses (MOVX
@
Ri),
Port 2 emits the contents of the P2 Special Function Register.
Port 2 also receives the high-order address bits during program verification.

Port 3
DPort 3 is an 8-bit bidirectional I/O port with internal pullups. Port 3 pins that
have 1s written to them are pulled high by the internal pullups, and in that state can be
used as inputs. As inputs, Port 3 pins that are externally being pulled low will source
current (I
IL
, on the data sheet) because of the pullups.
Port 3 also serves the functions of various special features of the MCS-51 Family, as
