    TIC12 = 1 / (mhz / 12)TIC6 = 1 / (mhz / 6)
    8-bit Timer Counter Maximum Run-Time for 12 clock = TIC12 * 256 / 1000
    8-bit Timer Counter Maximum Run-Time for 6 clock = TIC6 * 256 / 1000
    16-bit Timer Counter Maximum Run-Time for 12 clock = TIC12 * 65536 / 1000
    16-bit Timer Counter Maximum Run-Time for 6 clock = TIC6 * 65536 / 1000
    8-Bit DRT Reload Value for 12 clock = 256 -(DRT / TIC12 * 1000)
    8-Bit DRT Reload Value for 6 clock = 256 -(DRT / TIC6 * 1000)
    16-Bit DRT Reload Value for 12 clock = 65536 -(DRT / TIC12 * 1000)
    16-Bit DRT Reload Value for 6 clock = 65536 -(DRT / TIC6 * 1000)
