$2.$ You$$re asked to configure timer $0$ in mode $1$ to count every $25$ milliseconds.

Note: The $8051$ has a clock rate of $12$ MHz and is operating in STD mode.

a$.$ What is the $16-$bit reload value required for timer $0?$

b$.$ What value would be loaded into register TH$0?$

c$.$ What value would be loaded into register TL$0?$

d$.$ How should the registers in TCON be set to enable timer $0$ in mode $1?$

e$.$ How should the registers in TMOD be set to enable timer $0$ in mode $1?$

f$.$ What bits of register IEN$0$ need to be set to enable the timer $0$ interrupt?

g$.$ What address in program memory does execution branch to when

timer $0$ overflows with interrupts enabled?

h$.$ In the interrupt routine, what instructions should be performed, and in what order should they be performed in$,$ to safely reset the timer in mode $1.$ Explain the order of operations you have chosen.
