MwCSw”w.5D1atCaOSNhTeRetO4LUL.EcRom w PIN DESCRIPTIONS Vcc: Supply voltage. Vss: Circuit ground. Port O:Port O is an 8-bit open drain bidirectional 1/0 port. As an output port each pin can sink 8 LS TTL inputs. Port Opins that have 1‘s written to them float, and in that state can be used as high-impedance inputs. 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 pullups when emitting 1‘s. Dur- ing 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 dur- ing programming of the EPROM parts and during program verification of the ROM and EPROM parts. Port O is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory. In this application it uses strong inter- nal pullups when emitting 1‘s and can source and sink 8 LS TTL inputs. Port O also receives the code bytes during program- ming of the EPROM parts, and outputs the code bytes during program verification of the ROM and EPROM parts. External pullups are required during program verification. Port 1: Port 1 is an 8-bit bidirectional 1/0 port with internal pullups, The Port 1 output buffers can sink/ source
