Function Of Psen Pin In 8051 at Charlott Harrison blog

Function Of Psen Pin In 8051. The 4 i/o ports take up. The program store enable (psen) pin is the read signal pin for external memory and is active when low. Microcontroller the psen pin is used to access external code memory and is used as an input to determine whether to run user code or run the. Most of these pins are used to connect to i/o devices or external data and code memory. To interface with external memory, the 8051 microcontroller uses dedicated pins such as ale (address latch enable), psen (program store enable), and rd (read) and wr. It is connected to the output enable pin of external rom or eprom. Each of these pins can be configured as an input or an output. Each pin function is detailed below. The port pin p3.7 function as read control and the port pin. 8051 pin diagram consists of 40 pins. There are 40 pins on the 8051 chip. • the signal psen (low) is used as read control/enable for program memory.
