[1] SFRs are bit addressable.
[2] SFRs are modified from or added to the 80C51 SFRs.
[3] RESET value depends on reset source.
[4] Bit will not be affected by RESET.
8.1.1 Port characteristics
Port 0
Port 1
(P0.7 to P0.0): Port 0 is an open-drain, bidirectional I/O timer 2 generated
commonly used baud rates port. Port 0 pins that have logic 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 access to external
program and data memory. In this application, it uses strong internal pull-ups
when emitting logic 1s. Port 0 also outputs the code bytes during program
verification and received code bytes during EPROM programming. External
pull-ups are required during program verification.
(P1.7 to P1.0): Port 1 is an 8-bit bidirectional I/O-port with internal pull-ups.
Port 1 pins that have logic 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
