12.1 3-Wire Serial I/O (CSIn)
Remark
In this section, the value of n is as follows.
n = 0 to 3 (V850ES/SA2)
n = 0 to 4 (V850ES/SA3)
The 3-wire serial I/O (CSIn) transfers data using following three lines.
SCKn (serial clock)
SOn (serial data output)
SIn (serial data input)
The 3-wire serial I/O (CSIn) has the following features.
{
Transfer data length: Fixed to 8 bits
{
Transfer data MSB/LSB first can be switched
{
Transfer clock can be selected from eight clocks (seven master clocks, one slave clock)
{
Transmit/receive mode or receive-only mode can be specified
{
On-chip 8-bit transmit buffer
{
Transfer data transmit/receive timing with respect to the transfer clock can be changed
