Syntax

SPIOUT var , bytes

 

 

Syntax SPI1

SPI1OUT var , bytes

 

 

Remarks

var

The variable whose content must be send to the SPI-bus.

bytes

The number of bytes to send. Maximum value is 255.

 

When SPI is used in HW(hardware) mode, there might be a small delay/pause after each byte that is sent. This is caused by the SPI hardware and the speed of the bus. After a byte is transmitted, SPSR bit 7 is checked. This bit 7 indicates that the SPI is ready for sending a new byte.
