Manufacturer:FAIRC Description:Port 2: Port 2 is an 8-bit bi-directional 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 pulled low will source current because of the internal pull-ups. 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 emitting 1s. During accesses to external data memory that use 8-bit addresses (MOVX @Ri), Port 2 emits the contents of the P2 SFR. Some Port 2 pins receive the high order address bits during ROM reading and verification: |
