I’m trying to program the AFE031 Analog Frontend with a F28069 Microcontroller. Unfortunately there is some information missing about SPI programming in the AFE031 datasheet.
Maybe somebody has already experience in programming the AFE031?
It is written in the datasheet that a host SPI frame consists of a R/W bit, a 6-bit register address, and eight data bits.
First question: Is the following assumption correct?
R/W bit =1 performs Write Operation
R/W bit = 0 performs Read Operation
Second question: Each frame contains of 8 data bits. To write date to a AFE031 register do I have to transmit the MSB or the LSB first?
