Figure 13.9 Transmit Operation
• Example of transmit timing when transfer data is 8 bits long (parity enabled, one stop bit)
• Example of transmit timing when transfer data is 9 bits long (parity disabled, two stop bits)
The above timing diagram applies to the case where the register
bits are set as follows:
Transfer clock
UiC1 register
TI bit

The above timing diagram applies to the case where the register bits
are set as follows:
• UiMR register PRYE bit = 0 (parity disabled)
• UiMR register STPS bit = 1 (2 stop bits)
• UiIRS bit = 0 (an interrupt request occurs when transmit buffer
• UiMR register PRYE bit = 1 (parity enabled)
• UiMR register STPS bit = 0 (1 stop bit)
• UiIRS bit = 1 (an interrupt request occurs when transmit completed):
