Hi Duane,
No, the TMR0 register is only 8 bits wide, that's why you need to use the trick with getting the remaining count out of the prescaler.
So, RESULT is a total of 4 bytes where the two most significant bytes are the number of TMR0 overflows, the next byte is the TMR0 count (where each count equals 256 transitions of the inputsignal due the 1:256 presacaler ratio) and the least significant byte is the number of transitions "stored" in the prescaler.
