A
This function allows the setting two transfer clock output pins and choosing one of the two to output a
clock by using the port function select register (bits of related to-P6
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.
If the continuous receive mode enable bit (bits 2 and 3 at address 0370
032D
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.
This function works the same way as in the clock asynchronous serial I/O (UART) mode. The method
of setting and the input/output pin functions are both the same, so refer to select function in the next
section, “(2) Clock asynchronous serial I/O (UART) mode.” Note that this function is invalid if the
transfer clock output from the multiple pins function is selected.
When the data logic select bit (bit6 at address 033D
buffer register or reading from receive buffer register, data is reversed. Figure 17.6 shows the ex-
ample of serial data logic switch timing.
