(c) Transfer clock output from multiple pins function (UART1)
This function allows the setting two transfer clock output pins and choosing one of the two to output a
clock by using the CLK and CLKS select bit (bits 4 and 5 at address 03B016). (See Figure 1.14.3.)
The multiple pins function is valid only when the internal clock is selected for UART1. Note that when
_______ _______
this function is selected, UART1 CTS/RTS function cannot be used.

Note: This applies when the internal clock is selected and transmission
is performed only in clock synchronous serial I/O mode.

(d) Continuous receive mode
If the continuous receive mode enable bit (bits 2 and 3 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.
