Option Register
The Option register is a 6-bit wide, write-only register
which contains various control bits to configure the
Timer0/WDT prescaler and Timer0.
By executing the OPTION instruction, the contents of
the W register will be transferred to the Option register.
A Reset sets the Option<5:0> bits.
