In a given 8-bit general purpose micro-controller there are following flags: C = Carry, A = Auxiliary Carry, O = Overflow flag, P = Parity (0 for even, 1 for odd). R0 and R1 are the two general purpose registers of the micro-controller. After execution of the following instructions, the decimal equivalent of the binary sequence of the flag pattern [CAOP] will be ........ \texttt{MOV R0, +0x60}
\texttt{MOV R1, +0x46}
\texttt{ADD R0, R1}

An 8-bit ADC converts analog voltage in the range of 0 to +5 V to the corresponding digital code as per the conversion characteristics shown in figure.
