Figure 2.4.1. Memory map of serial I/O-related registers
Following are some examples in which various functions (a) through (g) are selected:
(6) Input to the serial I/O and the direction register
(7) Pins related to the serial I/O
(8) Registers related to the serial I/O
To input an external signal to the serial I/O, set the direction register of the relevant port to input.
• CTS
• RTS
• CLK
• RxD
• TxD
• CLKS
Figure 2.4.1 shows the memory map of serial I/O-related registers, and Figures 2.4.2 to 2.4.6 show
serial I/O-related registers.
• Transmission Operation WITH: CTS function, transmission at falling edge of transfer clock, LSB
• Transmission Operation WITH: CTS/RTS function disabled, transmission at falling edge of transfer
• Reception WITH: RTS function, reception at falling edge of transfer clock, LSB First, successive

Output pin for transfer clock. Can be used as transfer clock output pin in
Input pins for the CTS function
Output pins for the RTS function
Input/output pins for the transfer clock
Input pins for data
Output pins for data (Since TxD
needs pull-up resistor.)
