(3) Continuous receive mode
If the continuous receive mode enable bit (bits 2 at address 03B016, bit 5 at address 037D16) is set to
“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.
(4) Serial data logic switch function (UART2)
When the data logic select bit (bit6 at address 037D16) = “1”, and writing to transmit buffer register or
reading from receive buffer register, data is reversed. Figure 2.11.20 shows the example of serial data
logic switch timing.
