SPI ELECTRICAL & TIMING REQUIREMENTS
The following diagram and table summarize the SPI electrical and timing requirements. The SPI input and output levels are
set independently via the SPIVCC pin by connecting it to the desired supply. This would typically be tied to SW4 programmed
for 1.80 V. The strength of the MISO driver is programmable through the SPIDRV[1:0] bits.
