Table 1.14.4. Specifications of clock synchronous serial I/O mode (2)
Item
Specification
Select function
• CLK polarity selection
Whether transmit data is output/input at the rising edge or falling edge of the
transfer clock can be selected
• LSB first/MSB first selection
Whether transmission/reception begins with bit 0 or bit 7 can be selected
• Continuous receive mode selection
Reception is enabled simultaneously by a read from the receive buffer register
• Transfer clock output from multiple pins selection (UART1) (Note)
UART1 transfer clock can be chosen by software to be output from one of
the two pins set
_______ _______
• Separate CTS/RTS pins (UART0) (Note)
_______
_______
UART0 CTS and RTS pins each can be assigned to separate pins
_______ _______
Note 1: The transfer clock output from multiple pins and the separate CTS/RTS pins functions cannot be
selected simultaneously.
Note 2: Clock synchronous serial I/O mode cannot be used in UART2.
