Read-Only Author Meiring De Wet Posted 15-Dec-2006 07:50 GMT Toolset C51 |  Using external oscillator on MCB900 Meiring De Wet I am developing a system on the MCB900 dev.board and I want to use an external crystal to generate the clock @ 12MHz. What procedure do I have to follow to enable the crystal? | | Read-Only Author Andy Neil Posted 15-Dec-2006 07:59 GMT Toolset C51 |  RE: Using external oscillator on MCB900 Andy Neil http://www.keil.com/support/docs/2551.htm | | Read-Only Author Andy Neil Posted 15-Dec-2006 09:27 GMT Toolset C51 |  UCFG1 register Andy Neil From http://www.keil.com/forum/docs/thread8955.asp "I want to set up the MCB900 to use an external oscillator (12MHz),but I can't assign any values to the UCFG1 register to set up FOSC..How do I access UCFG1 to set the ext. osc, and do I have to configure P3.0 and P3.1?" Do you have to do this via FlashMagic? | |
