The monostable delay circuit is composed of a single operational amplifier connected as a voltage comparator. The circuit is shown in the attached figure. It has the characteristics of simple circuit ...
In 8051, is the only SFR sfr XX = 0x80; // (80H~FFH)?
Has anyone seen the following usage?
In 8051, SFR can only be sfr XX = 0x08;
Can this be changed in Keil? #define XX DBYTE[ 0x08]
sfr can sfr func...
