Answer / geo
program status word.... a reg in the
microcontroller/microprocessor s showing the current current
status of alu operation
eg: if a carry is generated after an alu operation ,the
corresponding carry flag bit in this reg will set 1.
like if the result is a zero, then the zero flag is set...
