Following are some examples in which various functions (a) through (c) are selected:
(6) Input to the serial interface special function and the direction register
(7) Pins related to the serial interface special function
(8) Registers related to the serial I/O
To input an external signal to the serial interface special function, set the direction register of the
relevant port to input.
• CLK
• RxD
• TxD
Figure 2.5.1 shows the memory map of serial interface special function-related registers, and Figures
2.5.2 to 2.5.7 show serial interface special function-related registers.
