#98265 - STOP! Responding to: ???'s previous message |
I am new on this forum and have recently started working with microcontrollers
and Like the author moves data 0ffh in port and then checks the status of bit 7 (DB7), which i guess would definately be high as we have moved FFh on that port. Am I write or I am missing something, STOP, do not go any further befrore you have read "the bible". Your question indicate that you need to get a speed course in the '51s architecture. Erik here are the links to "the bible" Chapter 1 http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf chapter 2 http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf chapter 3 http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf |
