13.13 Echo with Inversion (A5)

The Echo with Inversion command is used for testing the signal integrity and delays on I/O lines. It continues to

output data as long as CS is held low and SCK is being clocked. It alternates between transmitting the input data

value it received and the inverse value. It is mostly intended for use in octal mode, but can also be used in the other

modes for generating specific waveforms.

In octal mode, any value sent creates an alternating pulse train. The value entered with the command determines

the value of the first byte returned. The next byte is inverted, and so on. So a value of 00h or FFh causes all the I/O

lines to have the same value and alternate between 00h and FFh, while a value of AAh or 55h alternates between

AAh and 55h.

This command is not supported in SPI mode.
