CHAPTER 17 SERIAL INTERFACE CHANNEL 1
17.1 Serial Interface Channel 1 Functions
Serial interface channel 1 employs the following three modes.
• Operation stop mode
• 3-wire serial I/O mode
• 3-wire serial I/O mode with automatic transmit/receive function
(1) Operation stop mode
Operation stop mode is used when serial transfer is not carried out. Power consumption can be reduced.
(2) 3-wire serial I/O mode (MSB-/LSB-first selectable)
3-wire serial I/O mode transfer 8-bit data with 3-wires; serial clock (SCK1), serial output (SO1), and serial input
(SI1).
3-wire serial I/O mode can transfer/receive at the same time, so the data transfer processing time is fast.
The start bit of 8-bit data to undergo serial transfer is switchable between MSB and LSB, so it is possible to connect
to devices of any start bit.
3-wire serial I/O mode is valid for connection of peripheral I/O units and display controllers which incorporate
a conventional synchronous clock serial interface as is the case with the 75X/XL, 78K and 17K Series.
(3) 3-wire serial I/O mode with automatic transmit/receive function
This mode with the automatic transmit/receive function added to (2) 3-wire serial I/O mode functions.
The automatic transmit/receive function transfers/receives up to 32-byte data. This function enables the hardware
to transmit/receive data to/from the OSD (On Screen Display) device and device with on-chip display controller/
driver independently of the CPU, thus the software load can be reduced.
