6.2
The SPI Modes
The SPI module supports two (of the four) standard SPI
modes. These are Mode 0,0 and 1,1. The mode is
determined by the state of the SDI pin on the rising
edge of the 1st clock bit (of the 8-bit byte).
6.2.1
MODE 0,0
In Mode 0,0: SCK idle state = low (VIL), data is clocked
in on the SDI pin on the rising edge of SCK and clocked
out on the SDO pin on the falling edge of SCK.
6.2.2
MODE 1,1
In Mode 1,1: SCK idle state = high (VIH), data is
clocked in on the SDI pin on the rising edge of SCK and
clocked out on the SDO pin on the falling edge of SCK.
6.3
SPI Waveforms
Figure 6-3 through Figure 6-8 show the different SPI
command waveforms. Figure 6-3 and Figure 6-4 are
read and write commands. Figure 6-5 and Figure 6-6
are read commands when the SDI and SDO pins are
multiplexed on the same pin (SDI/SDO). Figure 6-7
are
increment and decrement
commands. The high voltage increment and decrement
commands are used to enable and disable WiperLock
Technology and Write Protect.
