This specification by design
This table is for the devices where the SPI’s SDI and SDO pins are multiplexed (SDI/SDO) and a Read
command is issued. This is NOT required for SDI/SDO operation with the Increment, Decrement, or Write
commands. This data rate can be increased by having external pull-up resistors to increase the rising
edges of each bit.
