(c) Transmission
If bit 7 (POWER0) of asynchronous serial interface operation mode register 0 (ASIM0) is set to 1 and bit 6
(TXE0) of ASIM0 is then set to 1, transmission is enabled. Transmission can be started by writing transmit
data to transmit shift register 0 (TXS0). The start bit, parity bit, and stop bit are automatically appended to
the data.
When transmission is started, the start bit is output from the T
followed by the rest of the data in order starting from the LSB. When transmission is completed, the parity
and stop bits set by ASIM0 are appended and a transmission completion interrupt request (INTST0) is
generated.
Transmission is stopped until the data to be transmitted next is written to TXS0.
Figure 13-8 shows the timing of the transmission completion interrupt request (INTST0). This interrupt
occurs as soon as the last stop bit has been output.
Caution After transmit data is written to TXS0, do not write the next transmit data before the
