For the System Start-up time values, whether fSYS is on or off depends upon the mode type and the chosen fSYS system oscillator. Details are provided in the System Operating Modes section. 2. tLIRC = 1/fLIRC 3. If the LIRC is used as the system clock and if it is off when in the SLEEP Mode, then an additional LIRC start up time, tSTART, as provided in the LIRC frequency table, must be added to the tSST time in the table above. 4. The System Speed Switch Time is effectively the time taken for the newly activated oscillator to start up. 5. For the HT68F0012, the system clock is from the IRC oscillator, and the fLIRC is equal to the fIRC divided by 16.

Dividing the voltage by this measured current provides the RPH value.
