21.4.1 Transmit Mode

When RCVEN (SENTxCON1[11]) = 0, the module operates as a transmitter. Message frames are generated using the Configuration and Data registers.

The module has two transmit operating modes selected by the TXM bit (SENTxCON1[10]). Asynchronous mode (TXM = 0) continuously sends data message frames when the ON bit (SENTxCON1[15]) is set. Synchronous mode (TXM = 1) sends messages under software control to support additional capabilities, including Short PWM Code (SPC).

A block diagram of Transmit mode is shown in Figure 21-3.
