Manufacturer:ON Description:Port 0 (AD0C7) C I/O. Port 0 is an openCdrain 8Cbit biCdirectional I/O port. As an alternate function Port 0 can function as the multiplexed address/data bus to access offCchip memory. During the time when ALE is high, the LSB of a memory address is presented. When ALE falls to a logic 0, the port transitions to a biCdirectional data bus. This bus is used to read external ROM and read/ write external RAM memory or peripherals. When used as a memory bus, the port provides active high drivers. The reset condition of Port 0 is triCstate. PullCup resistors are required when using Port 0 as an I/O port. |
