CHAPTER  12   SERIAL  INTERFACE  20 

12.1  Serial Interface 20 Functions 

Serial interface 20 has the following three modes. 

•

  Operation stop mode 

•

  Asynchronous serial interface (UART) mode 

•

  3-wire serial I/O mode 

 

(1)  Operation stop mode 

This mode is used when serial transfer is not performed.  Power consumption is minimized in this mode. 

 

(2)  Asynchronous serial interface (UART) mode 

This mode is used to send and receive the one byte of data that follows a start bit.  It supports full-duplex 

communication.  

Serial interface 20 contains an UART-dedicated baud rate generator, enabling communication over a wide 

range of baud rates.  It is also possible to define baud rates by dividing the frequency of the clock input to the 

ASCK20 pin.  

 

(3)  3-wire serial I/O mode (switchable between MSB-first and LSB-first transmission)  

This mode is used to transmit 8-bit data, using three lines:  a serial clock (SCK20) line and two serial data 

lines (SI20 and SO20). 

As it supports simultaneous transmission and reception, 3-wire serial I/O mode requires less processing time 

for data transmission than asynchronous serial interface mode. 

Because, in 3-wire serial I/O mode, it is possible to select whether 8-bit data transmission begins with the 

MSB or LSB, serial interface 20 can be connected to any device regardless of whether that device is 

designed for MSB-first or LSB-first transmission. 

3-wire serial I/O mode is useful for connecting peripheral I/O circuits and display controllers having 

conventional synchronous serial interfaces, such as those of the 75XL, 78K, and 17K Series devices.  

 

12.2  Serial Interface 20 Configuration  

Serial interface 20 includes the following hardware.  

 

Table 12-1.  Configuration of Serial Interface 20
