ok thanks, but where that came from? i cannot find that explicit information in any of the programming manuals

HELLO GUYS, FINALLY BACK!!!!!!!!!!!

Trying to resume my microcontroller proyects, i have a question about P0MDOUT register wich has to have a value to operate as push-pull. The fact is that in the example code:

P0MDOUT |= 0x04;                       // enable LED as a push-pull output (program in C)

orl   P0MDOUT, #04h           ; make LED pin output push-pull (program y assembler)

from keil webpage:

P1 |= 0x40;  // Generate ORL P1, 0x40

 Why ORL instead of simply MOV?, according with C8051F330/1-DS11 page 117 the  Port Output Mode registers (PnMDOUT) should be configured or SET, i can understand that to do this i only have yo assing a number to them. Any explanation for this?

BEST REGARDS
