Figure 1.15.16. Serial data logic switch timing
(c) Transfer clock output from multiple pins function (UART1)
(d) Continuous receive mode
(e) Serial data logic switch function (UART2)
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 03B0
The multiple pins function is valid only when the internal clock is selected for UART1.
If the continuous receive mode enable bit (bits 2 and 3 at address 03B0
set to “1”, the unit is placed in continuous receive mode. In this mode, when the receive buffer register
is read out, the SIO simultaneously goes to a receive enable state without having to write dummy data
to the transmit buffer register back again.
When the data logic select bit (bit6 at address 037D
reading from receive buffer register, data is reversed. Figure 1.15.16 shows the example of serial data
logic switch timing.
