The above applies under the following conditions:
i=0 to 4
The above applies under the following conditions:
1. Data transmission starts when BRG overflows after a value is set to the UiTB register on the rising edge of the TI bit.
2. Because the TxDi and RxDi pins are connected, a composite waveform, consisting of transmit waveform from the TxDi
3. Because the TxDi and RxDi pins are connected, a composite waveform, consisting of transmit waveform from the
4. The CNT3 to CNT0 bits in the TCSPR register selects no division (n=0) or divide-by-2n (n=1 to 15).
