#81929 - SPI or SPI?! Responding to: ???'s previous message |
According to the Atmel datasheet I'm looking at SPI means:
Serial Port Interface Are they actually talking specifically about SPI as in the Motorola 3/4-Wire bus, or is this just some other "local" usage of SPI? Which datasheet is it? As I said originally, there's a lot of sloppy usage about! ;-) http://www.8052.com/forum/read.phtml?id=81901 (See also http://www.8052.com/forum/read.phtml?id=46426 ) referred to thereafter as 'The SPI module'.
The chip most definitely does have an SPI in exactly the same way it has a UART. It is a physical object. No - as you just said, it has an "SPI module" and a "UART" SPI is the protocol; it is implemented in the SPI module. The SPI module is the physical object |
