5.6 Serial Interface 10
5.6.1 Functions of serial interface 10
Serial interface 10 has the following two modes.
Operation stopped mode
3-wire serial I/O mode
(1) Operation stopped mode
This mode is used to minimize power consumption when serial transfer is not performed.
(2) 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 line (SCK10) and two serial data lines
(SI10 and SO10).
As 3-wire serial I/O mode supports simultaneous transmission and reception, the time required for data
processing can be reduced.
In 3-wire serial I/O mode, it is possible to select whether 8-bit data transmission begins with the MSB or LSB,
allowing serial interface 10 to 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 effective for connecting peripheral I/O circuits and display controllers having
conventional clock synchronous serial interfaces, such as those of the 75XL, 78K, and 17K Series devices.
5.6.2 Configuration of serial interface 10
Serial interface 10 consists of the following hardware.
Table 5-10. Configuration of Serial Interface 10
Item
Configuration
Register
Transmission/reception shift register 10 (SIO10)
Control register
Serial operation mode register 10 (CSIM10)
(1) Transmission/reception shift register 10 (SIO10)
This is an 8-bit register used for parallel/serial data conversion and for serial transmission or reception in
synchronization with the serial clock.
SIO10 is set using an 8-bit memory manipulation instruction.
RESET input makes this register undefined.
