and data memory. In this application, it uses strong internal pull-ups when emitting 1s.
Ground: 0 V reference.
Ground: Additional ground pin (may be left open).
Ground: Additional ground pin (may be left open).
Power Supply: This is the power supply voltage for normal, idle, and power-down
operation.
Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s
written to them float and can be used as high-impedance inputs. Port 0 is also the
multiplexed low-order address and data bus during accesses to external program
Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups on all pins.
Port 1 pins that have 1s written to them are pulled HIGH by the internal pull-ups and
can be used as inputs. As inputs, port 1 pins that are externally pulled LOW will
source current because of the internal pull-ups. (See DC Electrical Characteristics:
I
Alternate functions for P8xC660X2/661X2 Port 1 include:
Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that
have 1s written to them are pulled HIGH by the internal pull-ups and can be used
as inputs. As inputs, port 2 pins that are externally being pulled LOW will source
current because of the internal pull-ups. (See DC Electrical Characteristics: I
Port 2 emits the high-order address byte during fetches from external program
memory and during accesses to external data memory that use 16-bit addresses
(MOVX @DPTR). In this application, it uses strong internal pull-ups when emitting
1s. During accesses to external data memory that use 8-bit addresses (MOV @Ri),
port 2 emits the contents of the P2 special function register.
Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that
have 1s written to them are pulled HIGH by the internal pull-ups and can be used
as inputs. As inputs, port 3 pins that are externally being pulled LOW will source
current because of the pull-ups. (See DC Electrical Characteristics: I
