I am programming a Cortex M3 bare-metal to talk with SPI Flash. One of the configuration bits of an SPI control register is
FRF (Frame format). It can either be set to SPI Motorola mode (0) or to SPI TI mode (1). (See the ARM reference manual page 695 here.)
The datasheet of the SPI Flash (available here) does not give indication regarding which mode I should use.
What are the two different modes, and which should I use for the specific Flash chip I am using?
