Clock synchronous serial I/O mode
(c) Transfer clock output from multiple pins function (UART1)
This function allows to set two transfer clock output pins and chooses one to output a clock by the setting of
CLK and CLKS selection bits (bits 4 and 5 at address 03B016). (See Fig.GA-12) The function is valid only
_______ _______
when the UART1 internal clock is selected. Note that when this function is selected, CTS/RTS function
cannot be used.

(d) Continuous receive mode
If the continuous receive mode enable bit (bit 3 at address 03B016) are 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.
