#160315 - 8051 cannot perform as a SOURCE Responding to: ???'s previous message |
David Prentice said:
... an 8051 cannot perform as a SOURCE whereas other micros can both SOURCE and SINK. That's the Classic 8051/8052 Port structure - as in the Intel original. Many modern derivatives do (also) have the option to source current - but that is device-specific and (usually?) does require you to configure it via some device-specific control register(s). As ever, you need to read the specific datasheet for details... |
