183 / 487 page  R8C/26 Group, R8C/27 Group 14. Timers Rev.2.10 Sep 26, 2008 Page 164 of 453 REJ09B0278-0210 14.2.1.1 Timer Write Control during Count Operation Timer RB has a prescaler and a timer (which counts the prescaler underflows). The prescaler and timer each consist of a reload register and a counter. In timer mode, the TWRC bit in the TRBMR register can be used to select whether writing to the prescaler or timer during count operation is performed to both the reload register and counter or only to the reload register. However, values are transferred from the reload register to the counter of the prescaler in synchronization with the count source. In addition, values are transferred from the reload register to the counter of the timer in synchronization with prescaler underflows. Therefore, even if the TWRC bit is set for writing to both the reload register and counter, the counter value is not updated immediately after the WRITE instruction is executed. In addition, if the TWRC bit is set for writing to the reload register only, the synchronization of the writing will be shifted if the prescaler value changes. Figure 14.17 shows an Operating Example of Timer RB when Counter Value is Rewritten during Count Operation. |
