(c) Normal transmission
When bit 7 (POWER6) of asynchronous serial interface operation mode register 6 (ASIM6) is set to 1, and
then bit 6 (TXE6) of ASIM6 is set to 1 after one clock of the base clock (f
enable status is entered. Transmission operation can be started by writing transmit data to transmit buffer
register 6 (TXB6). The start bit, parity bit, and stop bit are automatically appended to the data.
When transmission is started, the data in TXB6 is transferred to transmit shift register 6 (TXS6). After that,
the data is sequentially output from TXS6 to the T
stop bits set by ASIM6 are appended and a transmission completion interrupt request (INTST6) is generated.
Transmission is stopped until the data to be transmitted next is written to TXB6.
Figure 11-15 shows the timing of the transmission completion interrupt request (INTST6). This interrupt
occurs as soon as the last stop bit has been output.
