1.2.23.1.4 Continuous receive mode
If the continuous receive mode enable bit (bits 2 and 3 at address 03B0
"1", the unit is placed in continuous receive mode. In this mode, when the receive buffer register is read out,
the unit simultaneously goes to a receive enable state without having to set dummy data to the transmit buffer
register back again.
1.2.23.1.5 Serial data logic switch function (UART2)
When the data logic select bit (bit6 at address 037D
from receive buffer register, data is reversed. Figure 1.86 shows the example of serial data logic switch timing.
