Counter A starts counting of the base clock (BSCLK) when RARUN is set to “1” and the RCON signal (signal
synchronized with the fall of the base clock) is set to “1”.
automatically reset to “0” (6) and counting is terminated. At the same time, an RC-ADC interrupt request (RADIN)
occurs (7).
When the RCON signal is set to “1”, the RC oscillator circuit starts operation and Counter B starts counting of the RC
oscillator clock (RCCLK). When the RARUN bit is reset to “0” due to overflow of Counter A, RC oscillation stops
and Counter B stops counting.
The final count value “nB0” of Counter B is the RCCLK count value during the gate time “nA0 t
expressed by the following expression:
